This document summarizes information about wind energy and wind turbines. It explains that wind is caused by uneven heating of the earth's surface by the sun. Wind turbines convert the kinetic energy of wind into mechanical or electrical energy. There are two main types of wind turbines: horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT). HAWTs have the rotor and generator at the top of a tower and must face the wind, while VAWTs can accept wind from any direction but are less efficient. Wind turbines work by using the wind to turn blades connected to a generator to produce electricity without pollution. India has over 20,000 MW of installed wind power generation capacity across its states.
A wind mill converts the kinetic energy of moving air into Mechanical energy that can be either used directly to run the Machine or to run the generator to produce electricity.

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!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

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.

4. WIND ENERGY
Wind energy is a converted form of solar energy.
The sun's radiation heats different parts of the earth
at different rates-most notably during the day and
night, but also when different surfaces (for example,
water and land) absorb or reflect at different rates.
This in turn causes portions of the atmosphere to
warm differently.
Hot air rises, reducing the atmospheric pressure at
the earth's surface, and cooler air is drawn in to
replace it.
The result is wind.
5. WIND TURBINES
• Wind turbines are a rotating machine that will spin and
convert kinetic energy from the rotation in the wind into
mechanical energy or electricity to use to power your
house or anything else.
• There are various type of wind turbines these days.
• If they power machines directly such as a well pump
then they are considered wind mills.
• If the energy produced is instead converted to electricity
then the source is considered a wind turbine or wind
generator.
• Wind Turbines have subcategories like
Horizontal Wind Turbines
Vertical Axis Wind Turbines
6. HORIZONTAL AXIS WIND TURBINE
HAWT have the main rotor shaft and electrical
generator at the top of a tower
must be pointed into the wind.
Small turbines are pointed by a simple wind vane,
while large turbines generally use a wind sensor
coupled with a servo motor.
7. HORIZONTAL-AXIS WIND TURBINES
Small (<10 kW)
• Homes
• Farms
• Remote Applications
(e.g., water pumping,
Telecom sites, ice
making)
Large (250 kW-2+ MW)
• Central Station Wind Farms
• Distributed Power
• Schools
Intermediate(10-
250 kW)
• Village Power
• Hybrid Systems
• Distributed
Power
8. VERTICAL-AXIS WIND TURBINES
Vertical-axis wind turbines (VAWT) use rotors that run
vertically.
Three well-known types of VAWTs are the
1. Darrieus Wind Turbine - a model that collects
wind in cups dragging a turbine around,
and that looks much like a 'giant eggbeater
2. Giromill Wind Turbine - a subtype of Darrieus
turbine with straight, as opposed to
curved, blades.
3. Savonius Wind Turbine - a dragtype devise
consisting of two or three scoops causing a turbine to
spin,
9. VERTICAL-AXIS TURBINES
Advantages
Omni-directional
accepts wind from any
direction
Components can be
mounted at ground level
ease of service
lighter weight towers
Can theoretically use less
materials to capture the
same amount of wind
Disadvantages
Rotors generally near ground
where wind is poorer
Centrifugal force stresses
blades
Poor self-starting capabilities
Requires support at top of
turbine rotor
Requires entire rotor to be
removed to replace bearings
Overall poor performance and
reliability
10. HOW DO YOU CONVERT WIND INTO
ELECTRICITY???
Wind turbines convert the kinetic energy in the
wind into mechanical power.
This mechanical power can be used for specific
tasks (such as grinding grain or pumping water) or
a generator can convert this mechanical power
wind turbine works the opposite of a fan.
Instead of using electricity to make wind, like a fan,
wind turbines use wind to make electricity. The
wind turns the blades, which spin a shaft, which
connects to a generator and makes electricity.
11. HOW THE DOES A WIND TURBINE WORKS?
Wind turbines operate on a simple principle:
The energy in the wind turns the propeller-like blades
around a rotor. The pitch of the blades makes optimum use
of the wind direction.
The rotor is connected to the main drive shaft, which spins
a generator to create electricity.
Wind turbines are mounted on a tower to capture the most
energy. At 30 metres or more above ground, they can take
advantage of faster and less turbulent wind.
Wind turbines can be used to produce electricity for a
single home or building, or they can be connected to an
electricity grid for more widespread electricity distribution.

16. GENERAL ADVANTAGES
Wind energy is friendly to the surrounding environment,
as no fossil fuels are burnt to generate electricity from
wind energy
Wind turbines requires less space than average power
stations.
When combined with solar electricity, this energy source
is great for developed and developing countries to
provide a steady, reliable supply of electricity
Lowest prices renewable resources
Don’t produce atmospheric emissions that cause acid
rains and green house effects
17. GENERAL DISADVANTAGES
The main disadvantage regarding wind power is
down to the winds unreliability factor. In many
areas, the winds strength is not enough to
support a wind turbine
Wind turbines generally produce allot less
electricity than the average fossil fuelled power
station, which means that multiple wind turbines
are needed to make an impact.
