Determining the optimal placement scheme and height of elements that accelerate heat exchange processes in solar air heater collectors through mathematical modeling

Abstract

In the article, the heat exchange accelerating elements used in the collectors of solar air heaters were investigated by thermal and hydraulic mathematical modeling by changing the location scheme and geometric dimensions in homogeneous environment. In this case, the height of the gap between the flat absorber and the transparent glass was 60 mm. The height of elements that accelerate heat exchange processes has increased from 10 mm to 60 mm. The location scheme is laid out in a corridor and a checkerboard pattern. According to the modeling results, the results of the solar air heater collector with the rhombic heat exchange accelerating element were found to be high.
