“…One of the most popular techniques when dealing with fluids that have weak physical properties, such as air, water, etc., is channel structure optimization. Access to the use of obstacles, such as baffles, fins and ribs, is one of the best ways to improve the heat structure by enhancing the flow distribution inside the duct [1][2][3][4][5]. Some of the flows in finned, baffled, and/or ribbed channels under various situations are shown in tab.…”

This paper's numerical study, which applies the finite volume approach and SIMPLE algorithm, aims to dynamically analyze airflow through a channel with Z-obstacles. Three distinct models were used to place the Z-barriers inside the channel. According to Demartini et al.'s model (2004) and as depicted in example A from the present analysis, the first Z-barrier (fin) is attached to the top wall (heated) and the second (baffle) to the bottom wall (insulated). The Z-barriers, on the other hand, were positioned in the second model on the same wall (in-line arrangement), either on the top surface (two fins in example B) or on the bottom wall (two baffles in example C). With the help of these studies, fluid dynamics in solar air collectors with barriers will be better understood and designed.
