Turbulence Control Through Thermal Non-Equilibrium: Molecular Relaxation Models and Implications for Turbulencemodeling

Abstract

The main objectives are to explore the limitations of Landau-Teller model, develop multi-level alternatives for molecular exchanges, validate them against molecular simulations and state-of-the-art experiments, and understand the effect of different models for those exchanges in turbulence. Using this information the team will investigate the use of TNE to control turbulent fluctuations, in particular the reduction of turbulent fluctuations globally or locally in a flow. To achieve this objectives they will perform massive turbulence and molecular simulations, and conduct state-of-the-art experiments of hypersonic boundary layers to study the flow physics, understand turbulence-TNE interactions and develop better models.
