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 ...
