Impacts of Fin Variation on the Performance Of Shelf Type Solar Dryer

Abstract

This study is aimed to investigate the influence of using four types of fin (small wave, big wave, plate and zigzag) on the performance of shelf type solar dryer where the air flow applied in the study is the natural convection. Experiment method used in this study is by using four identical solar dryers in the same time. The different of these solar dryers is that each of them using different fin type. Research results show that waving fin yields the most optimum performance, followed by zigzag fin and fin plate. The lowest optimum performance is obtained from small wave fin.
