Performance Evaluation of Solar Air Heater by Using W- Discrete Rib Pattern
Keywords:
W-discrete ribs, Reynolds number, Heat transfer enhancement rate, Solar air heater.Abstract
Solar air heater effectiveness enhancement is the major criterion today. For the enhancement of efficiency of solar air heater relative roughness pitch plays a very important role. An experimental investigation has been performed to know about heat transfer rate, thermo hydraulic performance and friction factor of W-Discrete ribs in the form of artificial roughness of solar air heater. The relative roughness pitch (p/e) of the ribs was taken as 6 and 10 to studies its effect.
