The study of fluid motion using experimental and analytical methods is one of the scientific fields that has been considered today. With the advent of computer methods, humans have been able to study more complex phenomena. One of the scientific fields in which many advances have been made is computational fluid dynamics. In fact, computational fluid dynamics studies fluid behavior using new technologies and computational capabilities. In fluid dynamics, stagnation pressure (Pitot pressure) is the static pressure at a stable point in the fluid flow at a stable point, the fluid velocity is zero. In the present study, the stagnant pressure at the edge of the flow separating blade in rectangular channels was investigated in 18 models with different opening angles, baffle shapes and baffle arrangements. The modeling results show that the lowest stagnant pressure in the channel is created with an opening angle of 45 degrees and with convergent mode,and the maximum pressure was created in the channel with an opening angle of 60 degrees with the zigzag arrangement type.
