Solar collectors are the engines that drive all solar energy heating systems. Although solar heating collectors have settled upon a few basic designs, they are still manufactured in an array of configurations.Solar collectors are generally classified by the temperatures that can be produced under normal amounts of solar radiation. The collector’s end-use application can be determined by their temperature classification such as Low-temperature collectors, Medium-temperature collectors and High-temperature concentrators that track the sun and produces the highest temperatures.Reflectorsthat are axially symmetrical and shaped like a parabola, has the property of bringing parallel rays of light (such as sunlight) to a pointfocus and so any object that is located at its focus receives highly concentrated sunlight, and therefore becomes very hot. This is the basis for the use of this kind of reflector for high solar energy generation. Energy supply for domestic activities had been a major problem faced by both rural and city dwellers for a long time now in Africa. It was therefore desirable to design and construct a solar Fresnel reflector and a tracking stand that can be used to generate heat from the sun for cooking, baking and distillation purposes. The reflector and the tracking stand designed and constructed was able to concentrate solar energy within a regional diameter of 10cm and could be used to raise the temperature of any object placed at its focal region. It was discovered that the heat generated is directly proportional to both the perfection of the collector design, its construction, the quality of the reflectors e.g plain mirror, the area exposed to the sun and the solar intensity of the day.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

LECTURE 1 Solar Energy
• Energy produced by the sun
• Clean, renewable source of energy
• Harnessed by solar collection methods such as solar cells
• Converted into usable energy such as electricity
• Solar energy is the most readily available source of energy.
• It is free.
• It is also the most important of the non-conventional
sources of energy because it is non-polluting.
What is Solar Energy?
6. 6
LECTURE 1 Solar Energy
In the recent yeas there has been an extensive
increase in the use of solar energy.
For ex: Heating, cooling, power generation etc.
The radiation from sun is in the form of Direct
(Beam)radiation and Diffused radiation.
Hence at a particular location we need to measure
the irradiance data so that we can predict the
performance of solar energy.
7. Radiation is energy that comes from a source and travels through space
and may be able to penetrate various materials.
8. The bandwidth of radiant energy —
from long wave to short wave. It consists of radio waves, microwaves, visible light
(red and violet), ultraviolet rays, X rays, and gamma rays.
9. Definition
Solar constant is defined as the rate at which solar
energy arrives at the top of the atmosphere.
This is the amount of energy received from the Sun in
unit time on a unit of area perpendicular to the Sun’s
direction at Earth’s mean distance from the Sun.
• It is most accurately measured
from satellites where atmospheric effects are absent
•The value of the constant is approximately 1.366
kilowatts per square metre (1367 w/m2).
•The “constant” is fairly constant, increasing by only 0.2
percent at the peak of each 11-year solar cycle
•solar constant increases by about 10 percent every
billion years.
10. Solar Radiation at the Earth's Surface
• The solar radiation incident on the Earth's atmosphere is relatively constant,
the radiation at the Earth's surface varies widely due to:
1. atmospheric effects, including absorption and scattering;
2. local variations in the atmosphere, such as water vapour, clouds, and
pollution;
3. latitude of the location; and
4. the season of the year and the time of day.
• The above effects have several impacts on the solar radiation received at
the Earth's surface. These changes include variations in the overall power
received, the spectral content of the light and the angle from which light is
incident on a surface. In addition, a key change is that the variability of the
solar radiation at a particular location increases dramatically. The
variability is due to both local effects such as clouds and seasonal
variations, as well as other effects such as the length of the day at a
particular latitude.

Pyranometer
• PYRANOMETER
It is an instrument which
measures either global or
diffuse radiation falling on a
horizontal surface over a
hemispherical field of view.

Pyranometer
1) When sunlight falls on a pyranometer, the thermopile
sensor produces a proportional response typically in 30
seconds or less: the more sunlight, the hotter the sensor
gets and the greater the electric current it generates.
2) The thermopile is designed to be precisely linear (so a
doubling of solar radiation produces twice as much
current) and also has a directional response: it produces
maximum output when the Sun is directly overhead (at
midday) and zero output when the Sun is on the horizon
(at dawn or dusk).
3) This is called a cosine response (or cosine correction),
because the electrical signal from the pyranometer varies
with the cosine of the angle between the Sun's rays and
the vertical.

Sunshine Recorder
• The duration of bright sunshine is measured by means of
a sunshine recorder. The sun’s rays are focused by a
glass sphere to point on a card strip in a groove in a
spherical bowl mounted concentrically with the sphere.
Whenever there is a bright sunshine the image formed is
intense enough to burn a spot on the card strip. Through
the days the sun moves across the sky the image moves
along the strip. Thus the burnt space whose length is
proportional to the duration of sun shine is obtained on
the strip.

Solar water heater
• Fuel saving:
A 100 litres capacity SWH can replace an electric geyser for
residential use and saves 1500 units of electricity annually.
• Environmental benefits
SWH of 100 litres capacity can prevent emission of 1.5 tons
of carbon di oxide per year.
• Life : 15-20 years
The payback period depends on site of installation,utilization
pattern and fuel replaced.
Payback period :
3-4 years when electricity is replaced
4-5 years when furnace oil is replaced
5-6 years when coal is replaced

Solar collector
• Solar energy collectors are special kind of heat
exchangers that transform solar radiation energy to internal
energy of the transport medium.
• The major component of any solar system is the solar
collector.
• This is a device which absorbs the incoming solar radiation,
converts it into heat, and transfers this heat to a fluid
(usually air, water, or oil) flowing through the collector.
38. 38
Types Of Solar collector
1. Non-concentrating or stationary .
2. Concentrating.
1)Non-concentrating or stationary
A non-concentrating collector has the same area for
intercepting and for absorbing solar radiation, whereas a sun-
tracking. They can produce heat at low and medium
temperatures (up to 100 °C).
2) Concentrating.
Concentrating, or focusing, collectors intercept direct radiation
over a large area and focus it onto a small absorber area
.They can produce heat at high temperatures
39. 39
Stationary Collectors
• Solar energy collectors are basically distinguished by
their motion, i.e. stationary, single axis tracking and two
axis tracking, and the operating temperature.
• These collectors are permanently fixed in position and
do not track the sun

Flat plate collector
1. Glazing
2. Tubes, fins, or passages
3. Absorber plates
4. Headers or manifolds
5. Insulation
6. Container or casing
Components of FPC
44. 44
Flat plate collector
1. Glazing :- The glazing cover has the function of
isulating the solar collector from external
environmental conditions and allowing solar radiation
to pass through.
It is usually made up of a single sheet of solid glass
approximately 4mm thick.
This part is only present in glazed flat plate solar
collectors, designed to minimize heat loss.
2. Tubes, fins, or passages :- To conduct or
direct the heat transfer fluid from the inlet to the outlet.
3. Absorber plates :- The absorbing plate is the
element that intercepts solar radiation inside the collector and
is responsible for transforming solar energy into thermal
energy.
The absorbing plate is usually formed by a metallic foil,
usually copper (an excellent thermal conductor), that darkens.
Dark, matte bodies capture solar radiation better than any
other colour.
4.Headers or manifolds :- To admit and
discharge the fluid.
45. 45
Flat plate collector
5.Insulation :-
The insulation reduces heat losses from
the inside of the collector - specifically
from the absorbing plate - to the
outside. It is usually made up of
synthetic foam sheets (polyurethane,
cyanides, fiberglass, etc.) located on
the sides and the back of the solar
panel.
To minimize the heat loss from the back
and sides of the collector.
6.Container or casing :-
To surround the above mentioned
components and keep them free from
dust, moisture, etc.

Flat plate collector
Flat-plate collectors are the most common solar
collectors for use in solar water-heating systems in homes and
in solar space heating. A flat-plate collector consists basically
of an insulated metal box with a glass or plastic cover (the
glazing) and a dark-colored absorber plate. Solar radiation is
absorbed by the absorber plate and transferred to a fluid that
circulates through the collector in tubes. In an air-based
collector the circulating fluid is air, whereas in a liquid-based
collector it is usually water . Flat collectors can be mounted in
a variety of ways, depending on the type of building,
application, and size of collector. Options include mounting on
a roof, in the roof itself, or free.
Working Principle
47. 47

directions above the absorber.
2. flat-plate collectors do not need to track the sun
3. Simple in design
4. No moving part
5. Requires little maintenance
6. Less cost
Advantages
49. 49
Solar Dryer
Direct solar dryers expose the substance to be
dehydrated to direct sunlight. Historically, food
and clothing was dried in the sun by using lines,
or laying the items on rocks or on top of tents. In
Mongolia cheese and meat are still traditionally
dried using the top of the ger (tent) as a solar
dryer. In these systems the solar drying is
assisted by the movement of the air (wind) that
removes the more saturated air away from the
items being dried. More recently, complex drying
racks and solar tents[ were constructed as solar
dryers.
51. 51
Solar Still
A solar still distills water with substances dissolved in it by
using the heat of the Sun to evaporate water so that it may be
cooled and collected, thereby purifying it .. In a solar still,
impure water is contained outside the collector, where it is
evaporated by sunlight shining through clear plastic or glass.
The pure water vapour condenses on the cool inside surface
and drips down, where it is collected and removed. ...
The sun's energy heats water to the point of evaporation.
53. 53
Solar Cooker
A solar cooker is a device which uses the energy
of direct sunlight(generated from sunlight) to heat,
cook or pasteurize drink and other food materials.
Most solar cookers work on the basic principle:
Sunlight is converted to heat energy, that is used
for cooking. ... Evacuated tube solar cookers use
a highly insulated double-wall glass tube for the
cooking chamber, and do not require large
reflectors. Fuel: sunlight. Sunlight is the fuel.
A solar cooker converts solar energy into heat,
which is used to cook food kept in the cooking
utensil. Solar cookers also enable some
significant processes such as pasteurization and
sterilization
