Hello,everyone:
I want to compute the case that sound propagats in the fluid with background flow. The compute domain is assumed to be a square one and the problem is 2D. The background field are denoted as p0, U0 and rho0. I don't know how to apply the boundary for the sound pressure p and the paticle velocity U. Will the waveTransmissive BC work? and how to apply it  ? I cann't quite understand the information on openfoamwiki. (Now I just test the case that a gaussian pulse propagates and no reflect at the boundary).Thanks a lot. |
