This communication presents a second law analysis based on an exergy concept for a solar thermal power system. Basic energy and exergy analysis for the system components (viz. parabolic trough collector/receiver and Rankine heat engine, etc.) are carried out for evaluating the respective losses...

The energy and exergy analysis has been carried out for the different components of a proposed conceptual direct steam generation (DSG) solar–thermal power plant (STPP). It has been found that the maximum energy loss is in the condenser followed by solar collector field. The maximum exergy...

Utilisation of animal draft power in agricultural operation and milk production is highly dependent on the feed and fodder. Properly cooked feed is digestive in nature and enhance milk production. Solar energy is promising option for slow cooking. Keeping this in view a masonry animal feed solar...

Cooking is the prime requirement for people all over the world. It accounts for a major share of energy consumption in developing countries. Solar energy is contributing major energy requirements of the world's population particularly in developing countries. Among the different energy end uses,...

Solar energy is a clean, abundant and freely available renewable energy sources. Energy and exergy analysis of solar thermal devices has drawn considerable interest among the researchers across the world. Solar drying is the promising option to utilize low grade energy to dry agricultural...

Greenhouses provide a suitable environment for the intensive production of various crops. They are designed to provide control as well as to maintain solar radiation, temperature, humidity and carbon dioxide levels in the aerial environment. CO2 enrichment decreases the oxygen inhibition of...

Desalinated water, the final product of a solar distillation system, is useful for drinking purpose, community services, industry and agriculture on a small scale. It is expensive and may be considered as an industrial product. In the present communication, it has been tried to collect...

An analysis is presented for the performance of an inexpensive sand collector for solar energy which has been validated experimentally. The collector consists of a plane network of polythene pipes buried in a sand mass which is kept in a wooden case, the top surface of the sand being fixed by...

This paper describes an investigation of the periodic heat transfer and optimum placement of the air gap in a hollow concrete slab subjected to solar radiation and atmospheric air on one side and in contact with air at a fixed temperature on the other. The heat conduction equation has been...

In this paper, artificial neural network (ANN) models are developed for estimating monthly mean hourly and daily diffuse solar radiation. Solar radiation data from 10 Indian stations, having different climatic conditions, all over India have been used for training and testing the ANN model. The...
