Thermal and Mechanical Non-equilibrium Effects on Turbulent Flows Fundamental Studies of Energy Exchanges Through Direct Numerical Simulations and Experiments

Abstract

The effective life of this grant has been shortened by a superseding BRI, which include more ambitious and challenging research questions. During the six-month period of this grant, we have worked on the tasks and preparations for many of the issues detailed in the BRI. In particular, we have worked on baselines configurations that will serve as point of comparison when thermal non-equilibrium is introduced. The specific tasks were: (1) lay some of the theoretical framework for baselines flows, (2) develop the infrastructure for non-equilibrium studies, (3) mentor five graduate students, (3) study previous literature on compressible turbulence, turbulence shock interactions and photochemistry of LINE (Laser Induced Non Equilibrium) molecules, and (4) lay down framework to perform equilibrium turbulence interactions studies with a normal shock wave in hypersonic flow.
