Performance of Solar Air Heater System Using Different Shapes of Turbulators on the Absorber Plate
International Journal of Engineering and Creative science, Vol 1 (No 1): 31-35 (June 2018)
Abstract
This paper presents a performance analysis of three types of turbulators i.e V-shaped, Square shaped and Transverse wedge shaped turbulator on absorber plate of solar air heater system and are compared with flat plate collector. Effects of different turbulators on absorber plate of solar collector are studied and results are found out. The performance of turbulator used in this experimentation is evaluated in terms of heat transfer, Reynolds number, Nusselt number, Friction factor etc. The results shows that transverse wedge shaped turbulator have remarkable heat transfer enhancement and high Reynolds number as well as Nusselt number. It is also observed that heat transfer from transverse wedge shaped rib is more than that of flat plate collector.
