Abstract
An investigation of Improved Delayed Detached Eddy Simulation (IDDES) with Δy+-insensitive Near Wall Treatment (NWT) for prediction of turbulent heat transfer is performed in the framework of general-purpose CFD code ANSYS-Fluent for both fully attached and separated flows. The obtained results show that the considered approach is capable to predict the mean and RMS temperature with sufficient accuracy on the grids with the wall-adjacent step of about 1% of the velocity boundary layer thickness.
