Heat losses from a paraboloid concentrator solar cooker: Experimental investigations on effect of reflector orientation
The thermal performance of any focussing-type solar cooker, where an unglazed/uuninsulated cooking pot is often used, depends to a great extent on wind conditions. Moreover, these cookers need frequent adjustments to track ...
Effect of wind on the thermal performance of a parabolloid concentrator solar cooker
Thermal performance of a parabolloid concentrator solar cooker depends greatly on the wind speed. Experiments have been conducted to study the effect of wind speed on heat loss parameter F′UL and hence on thermal performance ...
Energy engineering education at postgraduate level: Issues involved, course structure and its proposed adaptation
Some basic issues involved in providing energy engineering education at postgraduate level are briefly discussed. Salient features of a proposed teaching programme in energy engineering are described. Finally, suitable ...
Testing of a prototype combined photovoltaic-thermal linear fresnel concentrator-receiver system
Results of some preliminary experiments conducted on a combined photovoltaic-thermal concentrator-receiver system comprising a linear Fresnel reflector (concentrator) and a rectangular channel mounted with solar cells ...
Preliminary study of water boiling test procedures used for performance evaluation of fuelwood cookstoves
A critique of the water boiling test procedures developed over the last decade for fuelwood cookstoves is presented. Results of some preliminary tests conducted on single- and double-wall fuelwood cookstoves are presented, ...
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.
Testing of box-type solar cooker: Second figure of merit F2 and its variation with load and number of pots
The performance of a box-type solar cooker can be represented in terms of two figures of merit, F 1 and F 2. The second figure F2 is a controlling factor in the sensible heating of a load. The present work validates F 2 ...
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, ...
Financial feasibility analysis of box-type solar cookers in india
A framework for financial evaluation of a box-type solar cooker, using cost functions for its capital cost, has been developed. The annual benefits accrued to the user are quantified in terms of number of meals cooked per ...
