Investigation of Suitability of SST k-ω Turbulence Model with Low-Reynolds Number Correction for Impinging Jet Flow in Different Geometries and Thermal Boundary Conditions

Thermal jet flows are the type of flow frequently encountered in engineering applications. This article aims to determine if the SST k-ω turbulence model, including Low-Reynold Correction, accurately estimates the Nusselt number in impinging jet flow; because of this, computational results were compared with experimental studies. This comparison was made on a line (r/D) from stagnation point to exit. In this article, the heat transfer phenomenon in the impinging zone was observed computationally with the SST k-ω turbulence model on three impinging jet geometries with different boundary conditions using ANSYS FLUENT software. The boundary condition on the upper plate differs depending on whether there is confinement. The boundary condition on the impinging plate differs depending on whether there is a heat flux or fixed surface temperature. The flow type is a steady state. The software solver type is pressure-based because the flow velocity is too low compared to the local sound velocity.
