"Variable turbulent Prandtl number model for Shock-Boundary Layer Interaction flows"
High speed turbulent flows with shock waves are characterised by high localised heat transfer rates. The conventional turbulence models used for predicting these high surface heat flux values routinely over-predict the same and are thus inadequate. The turbulent Prandtl number has been identified as the parameter of interest as it is a major factor in modelling of the turbulent heat flux. It is conventionally taken as a constant number for RANS based numerical simulations even though it is a turbulence dependent quantity and varies along the flow. The characteristics of turbulent Prandtl number based on the experiments and DNSs have been studied and an algebraic mathematical model for varying turbulent Prandtl number has been proposed for accurate prediction of surface heat flux for the case of SBLI flows. The proposed model provides a significant improvement in surface heat flux prediction while adding a negligible computation cost.
