A comparative study of various types of artificial roughness geometries in the absorber plate of solar air heater duct and their characteristics, investigated for the heat transfer and friction characteristics, has been presented. The performance evaluation in terms of ηI, ηef and ηII has...

The solar thermal power plant is one of the promising renewable energy options to substitute the increasing demand of conventional energy. The cost per kW of solar power is higher and the overall efficiency of the system is lower. In the present communication, a comprehensive literature review...

Energetic and exergetic analysis has been carried out for the components of the solar thermal power plant system (parabolic trough collector/receiver and Rankine heat engine). The energetic and exergetic losses as well as efficiencies for typical parabolic trough concentrating solar thermal...

Heat exchangers are thermal systems which are used extensively, have a major role in energy conservation aspect and preventing global warming. This paper is based on reviews of scientific work and provides a state-of-the-art review of second law of thermodynamic analysis of heat exchangers....

Purpose – The ventilation and air-conditioning systems consume the highest energy in the building sector. The proper ventilation in residential buildings through the passive solar systems can substantially reduce the energy consumption in building sector. The paper aims to identify the...

Some of the issues relating to renewable energy education are highlighted. Outlines of proposed course curricula for certificate and Diploma level courses are briefly presented and discussed.
