Hello all,


I have a rather unique situation that I am not sure exactly how to handle. I am using the kw-SST model to resolve the heat transfer coefficients on an impingement surface at which the y+ is < 1. For this I need the k-w SST model as its one of the best for the impingement case. However my model also has inlet pipes that I don't care about wall fluxes and am simply developing a velocity profile. I would resolve these inlets to a y+ of 1 although the geometry is very prohibitive causing inflation to be not exactly an option and the number of cells needed to be very high.

My question is essentially If I leave the y+ at the inlet pipes greater than 1 in the 30-100 range. Is the kw sst model defaulting to wall functions or will it attempt to resolve and give garbage results? Should I just remove the inlet pipes and develop a separate velocity profile?
