pipe dia = 21mm

hole size = 5 - 8.5mm at equal distance

around 1.7M cells with inflation on the pipe wall (stair step mesh), proximity sizing for each hole and hole enclosure, minimum orthogonal quality 0.2. 

velocity profile (target average velocity should be 6.5 m/s)

 

pressure: (target pressure drop 32 Pa, i am getting 36Pa)

Do you think i should enable transition model as well (I think its more apt for moving surfaces which ia not my case) to reduce the pressure drop?Â
