Hypersonic Applications: Physical Models for Interdisciplinary Simulation

This unique 8-hour short course is meant to introduce students to physical models for interdisciplinary simulation of hypersonic applications, emphasizing on introduction and evaluation of various physical models. 

Overview

Hypersonic numerical simulation developments and improvements are critical to the advancement of current and future sustained high-speed flights and interplanetary explorations. In order to achieve a higher degree of fidelity for the high-enthalpy hypersonic flows, physical models must venture into an interdisciplinary domain by integrating chemical kinetics, ionization, quantum transition, radiation, and electromagnetics with aerodynamics. This unique 8-hour short course is meant to introduce students to physical models for interdisciplinary simulation of hypersonic applications, emphasizing on introduction and evaluation of various physical models. Topics include internal energy excitations, non-equilibrium chemical kinetics, transport properties (diffusivity, viscosity, and thermal conductivity), energy relaxations, radiative heat transfer, weakly ionized gas, and surface ablation.
