Abstract
In this study, turbulence models and near-wall modeling approaches were compared in impingement heat transfer. The Reynolds-averaged Navier-Stokes (RANS) turbulence models were compared using three near-wall modeling approaches. Moreover, the effect of near-wall modeling approaches on heat transfer was investigated and the predictions were compared with experiments. All computations were performed with the FLUENT code by considering two-dimensional, steady, and incompressible flow. Wall functions (WF) should be used carefully in conjunction with turbulence models, and the enhanced wall treatment (WT) is suggested for practical applications. The standard k-epsilon model showed the best agreement with the experimental data among the models used under the considered conditions.
