Abstract

The study focuses on solar dryer machines that employ a mixed mode and a double-pass solar collector. Some challenges must be solved and the collector's performance and efficiency must be improved to use solar energy for food preservation correctly. Hence, to design the best solar collector, research and analysis are conducted to examine the effects of various fin configurations on the behaviour of the airflow in a double-pass solar collector system. Thus, several fin arrangements, including straight, staggered, and pin fins, will be employed in this study. The top cover is composed of glass, while the solar collector is entirely constructed of stainless steel. The Ansys Fluent tool is used to execute the simulation. To maximise convective heat transfer within the collector, it is crucial to comprehend these airflow complexities. Material properties like density, thermal conductivity, and specific heat are assigned for materials stainless steel and glass. These arrangements will have an impact on how the airflow is distributed in the collector. In this research, ANSYS simulations will be used to track the thermal efficiency of the solar collector by considering the streamline, velocity, and pressure in the solar collector system.
