AB - 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.
