Abstract

Due to the high cost of solar air heating systems, performed a parametric analysis to find ways to improve their efficiency. Solar air heating systems with ribs, a novel design, are the subject of the research. Carry out a numerical investigation of a "solar air heater" in "ANSYS Fluent" using "computational fluid dynamics" (CFD) for this work. Enhanced the absorber plate by modifying the pitch and adding more ribs. In order to get the best possible outcome, it was necessary to evaluate the outlet temperature, air temperature inside the duct, friction factor, and heat transfer rate. Case 4, having a maximum outlet temperature, air temperature inside the duct, friction factor, and heat transfer rate with increment of 4.75 %, 1.11%, 35.5%, and 5.52% from case 1 respectively.
