Thermal Analysis of a Solar Air Heater for Drying Purposes

Abstract

In this study, energetic efficiency of a solar air heater with aluminum flat plate absorber was examined experimentally for airflow velocity of 2, 3 and 4 m/s. An experimental setup was built-up and experiments were compared with the results of the analysis performed by using computational fluid dynamics (CFD) software. Results were also evaluated based on thermographic camera images.
