The top cover of a flat 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 horizontal surfaces exposed to forced air flow, produced by industrial fans...

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 the Sun in order to keep the focus always at the bottom of the cooking...

The paper presents a simple test procedure for determination of design parameters to predict the thermal performance of a box-type solar cooker. A series of out-door experiments were performed on the double-glazed solar cooker of aperture area 0.245m2 with a fibre body to obtain two figures of...

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...

Three somewhat different experimental test procedures may be employed for the determination of the optical efficiency factor, F′ηo, of a parabolloid concentrator solar cooker. The procedures are briefly described and typical results presented. The merits and drawbacks of each test procedure...

This paper presents simple thermal analysis to evaluate the natural convective heat transfer coefficient, hc12 for a trapezoidal absorber plate-inner glass cover enclosure of a double-glazed box-type solar cooker. Several indoor simulation experiments in steady state conditions have been...
