ABSTRACT

In the present investigation, the theoretical model for air temperature rise and hence efficiency have been developed to investigate the thermal performance characteristics of solar air heater having wavy fins on absorber plate. The effect of area enhancement factor, fin spacing and mass flow rate on thermal performance has been presented and results are compared with plain fins and without fins. It is observed that considerable enhancement in the collector efficiency of a flat-plate solar air heaters is obtained if collectors are constructed with wavy fins and this enhancement is strong function of system and operating parameters.
