Abstract :
Knowledge of wind heat transfer coefficient, hw, is required for estimation of upward losses from the outer surface of flat plate solar
collectors/solar cookers. In present study, an attempt has been made to estimate the wind induced convective heat transfer coefficient by
employing unglazed test plate (of size about 0.9 m square) in outdoor conditions. Experiments, for measurement of hw, have been conducted
on rooftop of a building in the Institute campus in summer season for 2 years. The estimated wind heat transfer coefficient has
been correlated against wind speed by linear regression and power regression. Experimental values of wind heat transfer coefficient estimated
in present work have been compared with studies of other researchers after normalizing for plate length.
