Numerical study of a turbulent impinging jet for different jet-to-plate distances using two-equation turbulence models

The near-wall grid resolution at the target plate has been varied for a jet-to-plate distance of H/D=6. The results show the influence of the dimensionless distance of the first node near the wall on flow and heat transfer characteristics. A comparison of a hybrid and a block-structured grid assesses the influence on the mesh topology.
