Description

Enabling high fidelity simulations of entry and re-entry turbulent flow environments requires the generalization of scaling laws and new fundamental understanding describing the interaction of turbulence with shock waves, finite-rate reactions, surface catalysis and ablation, and radiation. The use of direct numerical simulation data to extend turbulence scaling and advance turbulence models for high enthalpy conditions will be described, including on-going work to account for surface catalysis, roughness, and blowing and transpiration that is found in ablating environments.
