Against a backdrop of our world’s changing climate solar thermal power generation shows great potential to move global energy production away from fossil fuels to non-polluting sources. A parameter study was conducted based on the previous analysis to improve specific aspects of the initial design using a value of benefit analysis to evaluate the different design. This project focused on the design, analysis and verification of a high temperature solar receiver. Computational Fluid Dynamic (CFD) analysis of Radiation model is carried out with new geometry design of receiver. Discrete Transfer Radiation Model (DTRM) model is used for numerical simulation.
Concentrated solar power (also called concentrating solar power, concentrated solar thermal, and CSP) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. Electricity is generated when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator.

COMPARATIVE STUDY OF PARABOLIC TROUGH CONCENTRATORS IAEME Publication
In the present work two parabolic trough concentrator system of different rim angle and
different reflector aperture area is designed, fabricated, and evaluated, and operated for generate hot
water .There one system is 45° rim angle and next is of 90° rim angles, here reflector aperture area of
45° rim angle has operatically 20% more than 90° rim angle system, but remaining all other features
are same for both the 90° and 45° system. On operation of the system we gets nearly same efficiency
for both the system thus we observe that for all same equal features except of reflector aperture area,
the efficiency got 20+% more for 90° rim angle compare to 45° rim angle.
Development of a Solar Fresnel Reflector and Its Tracking Stand Using Local M...IJERA Editor
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.

STUDY OF SOLAR THERMAL CAVITY RECEIVER FOR PARABOLIC CONCENTRATING COLLECTOR ijiert bestjournal
Energy is one of the building blocks of the country . The growth of the country has been fueled by chea p,abundant energy resources. Solar energy is a form of renewable ener gy which is available abundantly and collected unre servedly. The parabolic concentrator reflects the direct incident solar rad iation onto a receiver mounted above the dish at it s focal point. The conversion of concentrated solar radiation to heat takes place in receiver. The heat transfer characteristics of the receiver changes during the rotation of the receiver which affects thermal performance. The working temperature may also influence the ther mal performance and overall efficiency of the system. Thermal as well as optica l losses affect the performance of a solar paraboli c dish-cavity receiver system. The thermal losses of a solar cavity receiver include c onvective and radiative losses to the air in the ca vity and conductive heat loss through the insulation used behind the helical tube surface. Convective and radiative heat losses form the major constituents of the thermal losses. The convection heat loss from cavit y receiver in parabolic dish solar thermal power sy stem can significantly reduce the efficiency and consequently the cost effectiveness of the system. It is important to assess this heat loss and subsequently improve the thermal performance of the receiver.

In this day and age of connected living, it is critical for people to interface the wellbeing factors and health conditions into trends so as to picturize the state of health of an individual. In addition, it is essential to include the wearables and therapeutic gears to viably speedup up the treatment cycle. It is equally important to pull health records and scanned images from various systems which follow different standards and ensure that they interact appropriately. These interactions could either be driven from the clinics and hospitals, or performed as a part of awareness by the end users (patients and health conscious individuals). To understand these interactions, we have taken Diabetes management as our use case. Diabetes is turning into a lifestyle disease and hence is an ideal candidate since we need to monitor the health conditions of the patient continuously. The vital parameters of the body could either be monitored through medical devices and equipment, body sensors, mobile applications, or wearables.This paper analyses the solutions proposed so far for effective diabetes management using cloud technology. The paper also touches upon IoT-based solutions which could be used to treat chronic ailments from remote locations.

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.
