UDF: DEFINE_PROFILE_Velocity Inlet for 2D Axisymmetric Flows with Swirl
 

Hello,

could somebody help me to specify the velocity inlet boundary conditions for a 2D axisymmetric flow with swirl.

My target is to set the velocity Inlet considering

r = 0 ~ 0.0425 m (radial coordinate set as variable)
u = 11 m/s (axial velocity set as const.)
v = 0 (radial velocity set as const.)
w = 8*r (swirl velocity set as variable)

many thanks in advance!
