WebDescription Project Description. An impinging jet is a fluid jet that strikes a surface vertically or at a specific angle for cooling or heating. In this case, the post-impact flow develops on the surface, creating a thermal boundary layer. As it moves in a peripheral direction, the thickness of this boundary layer increases, and consequently, the rate of heat transfer … Webno wall functions accurate near wall overestimates turbulence in regions with large normal strain (better than k–ε, however) converges slowly (use other model for initial guess) … church of scotland glasgow city centre
