If the walls don't allow heat transfer and there is no other heating effect how much do you expect the density to change? Re the mesh, for multiphase we also need a relatively low aspect ratio, this can be at odds with the text book y+ requirements. Either increase the streamwise resolution or reduce the near wall resolution. I'd also favour a quad pave over O-grid to avoid jumps in cell size.
