“…By and large, flow through porous media is accompanied by high‐pressure drop 17–22 . In an exceptional case represented by using a porous medium as an absorber plate in SAHs, despite the high‐pressure drop associated with this modulation, it is considered immaterial as compared with the thermal performance enhancement, particularly in high porosity materials 23–27 . In many previous articles, the wire mesh was used as a porous absorber plate.…”

The drying process is considered an effective technique for preserving foods and agricultural products from spoilage. Moreover, the drying process lessens the products' weight, volume, and packaging, which prompts a reduction in the products' transportation costs. The drying technique with solar energy represents an ancient method, still alluring due to solar energy abundance and cost‐effectiveness. In this article, the previous manuscripts concerned with studying and analyzing indirect solar dryer systems that utilize innovative solar air heaters (SAHs) are reviewed. The results and conclusions are discussed intensively to clarify the significance of utilizing this type of drying technique. The effect of many parameters on the thermal performance and efficiency of the dryer systems has been investigated. The investigated parameters included the incident solar radiation, air flow rates, outlet solar air heater temperature, absorber plate material, moisture content of the agricultural products, and the shape and configuration of the SAH. Moreover, the manuscript outlines the drying rate mathematical models that were used to validate the experimental findings. Based on the review, it is found that solar dryer systems with modified SAHs designs rather than flat plate SAH have considerable effects on enhancing thermal performance and efficiency.

Increasing the absorber plate surface in a solar air heater system (SAHs) can increase thermal efficiency, heat transfer coefficient, and Nusselt number. This paper includes the development of a 3-dimensional computational fluid dynamics (3-D CFD) model for predicting the location of the absorber plate from the bottom of the collector, followed by its validation using experimental data. Various geometrical types are investigated to determine optimal design features, such as Type I, Type II, Type III, Type IV, and Type V. A comprehensive analysis is performed to achieve this goal, including thermal efficiency, heat transfer coefficient, and Nusselt number analyses. Results indicate that Type V has better performance than other geometries. When the absorber plate location Type V with a distance (dis) of 0.012 m far from the bottom of the collector. As a result, increases in the average thermal efficiency, heat transfer coefficient, and Nusselt number of the system are 19 %, 53%, and 268.8%. Compared to Type I, when the absorber plate was lying on the collectors without a gap between the absorber and collector bottom.
