I'm simulating a multiphase flow that includes continuous and dispersed phase. The flow should pass through a wall. When I define dispersed phase as circles in Gambit, drops adhere to the wall, while when I inject drops by nuzzle they don't adhere to the wall. Could everyone help me?
I'm so grateful if anybody can help.
Thanks.

Could you please elaborate the problem? such as whether 2D or 3D case, Was the wall porous? else how does the droplet pass through it? R u injecting droplets from the nozzles( DPM injection or bulk fluid)? if it is , is it evaporating spray with medium drag forces active then?... please clarify.

best regards
