Study of a hybrid solar system—solar air heater combined with solar cells
In a conventional solar thermal system, electrical energy is needed to circulate the fluid. This energy is supplied by an electrical source. A hybrid system, a combination of thermal and photovoltaic systems can generate ...
Studies on semi-cylindrical solar tunnel dryers: thermal performance of collector
In this paper, the modelling and thermal performance results of the collector of a semi-cylindrical solar tunnel dryer (STD) have been presented. The performance has been estimated under natural circulation as well as under ...
Design analysis of corrugated and flat plate solar air heaters
A detailed theoretical parametec analysis has been made on corrugated and flat plate solar air heaters of five differentconfigurations. The analysis involves investigating the effects of the air flow velocities (or the air ...
Performance Studies of a Passively Cooled Mahal
The design and performance of an ancient passively cooled mahal (building) have been presented. The mahal was generally used for pilgrims during their visit to the city of Banaras. Energy balance equations for different ...
Effect of Baffle Plate on The Perf Ormance of a Triangular Built-in-Storage Solar Water Heater
The triangular design of a solar water heater not only enhances the overall gain to the system but also improves the natural convection between the absorbing plate and the water, leading to better performance of the system. ...
Conventional hybrid photovoltaic/thermal (PV/T) air heating collectors: steady-state simulation
This investigation is concerned with the performance analysis of a con-ventional hybrid photovoltaic/thermal air heating collector. A simulation model is developed and various performance parameters are calculated for ...
Renewable energy education:challenges and problems in developing countries
Development and dissemination of efficient and economic techniques of harnessing new and renewable sources of energy to bridge the ever increasing gap between the energy demand and supply in developing countries is a ...
Energy demand and supply options for primary processing of rice in India
Energy demand for primary processing of rice in India has been assessed and feasibility of two renewable energy supply options evaluated. A model for obtaining least cost energy supply mix for a rice mill has been proposed.
Solar energy for paddy parboiling in India: financial feasibility analysis
Low-efficiency, rice-husk-based furnace-boiler systems are generally used for meeting thermal energy demand of paddy parboiling in India. Shortages in rice-husk availability are met with fuels such as coal, furnace oil, ...
An attempt to present briefly some important aspects of energy-education as an emerging discipline is made in this paper. Suggestions concerning the evolvement of an effective approach for energy-education at all levels ...
