The objective of this study is to improve the two-equation heat-transfer turbulence model so as to accurately predict impinging jets with heat transfer. First, we have assessed existing modeled expressions of Reynolds stress and turbulent heat-flux with the aid of a direct numerical simulation (DNS) database. Then, in order to confirm the performance of existing two-equation heat-transfer models for impinging jets, we have carried out numerical simulation in a plane impinging jet with heat transfer. It is found that none of the existing models can adequately predict the correct behavior of statistical turbulence quantities obtained in the DNS. Based on these assessments, we have reconstructed the improved Reynolds stress expression, and obtained the improvements necessary for the two-equation heat-transfer model.
