parabolloid concentrator solar cooker; wind speed; heat loss parameter
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 of the cooker under simulated wind conditions. Correlations have been developed to express the F′UL as a function of wind speed and pot water temperature. Heating characteristic curves have been also developed with the variable values of F′UL and compared with those obtained from constant F′UL.
