Greetings to all;

I'm trying to conduct 2D nonequilibrium turbulent boundary layer analysis on flat plate with OpenFOAM v2212. To impose pressure gradient effects on the boundary layer, I create suction at top boundary of the domain. Thus, besides the inlet velocity condition, I have also the top velocity condition, which imported from the CSV file.

I'm using k-w SST model with mesh y+ ~ 1. I've used simpleFoam and pisoFoam to obtain convergence in analyzes. However, I have some stability and convergence issues with k-w SST model especially at the top boundary. I observed irrelevant x-component of velocity contours.

I wonder if there is someone who can do this kind of analysis before and help me? Any suggest would be helpfull.

Thanks in advance.
