Statistical Study of Thermal Analysis in Solar Air Heater System Using Inclined Discrete Rib

Heat is transferred in a solar air heater (SAH) system between air and absorber portion. A solar collector that exhibits low air-to-absorbing plate transmission of heat will exhibit inadequate overall thermal performance. Employing artificial roughness that encourages heat transmission from the absorber plate might be an effective approach to improve it. This technique has been adopted by researchers progressively more in their work for an extensive amount of time, so further research into it is still possible. In an attempt to enhanced natural convection, artificial roughness has been added to the collector in this investigation. The most suitable improvements for collectors are presented here. Collectors can find models with an inclined, distinct rib structure. To investigate the thermal performance, turbulent airflow through the specifically roughened solar collector system has been generated using computational fluid dynamics (CFD) application in Fluent of ANSYS. A standard absorber plate collector employing CFD has been used to compare performance of the modified collectors. It has been established that enhancing the absorber plate collector's synthetic roughness characteristics enhanced an overall performance system of solar thermal collector. Eventually, the outcome of thermal performance in modified collector performed more effectively than the traditional collector. In the final analysis, the computer-simulated thermal efficiency became 2.27 when compared to an experimental investigation of 1000 W/m<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> heat flux.
