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 ...
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 ...
Wind induced heat losses from outer cover of solar collectors
The top cover of a fiat plate solar collector is generally exposed to wind. In indoor experiments it is necessary to simulate this wind. Correlations have been developed for the wind heat transfer coefficient over flat ...
Experimental test procedures for determination of the optical efficiency factor of a parabolloid concentrator solar cooker
Three somewhat different experimental test procedure may be employed for the determination of the optical efficiency factor,Fn,of a parabollied concentrator solar cooker.The procedure are briefly discribed and typical ...
Top heat-loss factor of double-glazed box-type solar cooker from indoor experiments
The top heat-loss factor (Ui) of a box-type solar cooker varies with plate temperature, wind heat-transfer coefficient and ambient temperature. A method for correlating Ui with these variables is presented for a cooker ...
