Hi,nIs your flow turbulent? Also, why only 5 layers in the Boundary layer? You would need ~15 - 20 layers to accurately capture the gradients near the wall.nAlso, why are you taking just the static pressure? Shouldn't you be taking the difference in the total pressure here?nHave you run any mesh independence studies?nYou might need to create a refined mesh near the value because there is likely going to be flow separation and reattachment. If you do not capture this properly, you will not get the correct pressure drop.nKarthikn
