Radiative Heat Transfer Measurements in a Nonreflected Shock Tube at Low Pressures
At high flight speeds, radiation becomes an important component of aerodynamic heat transfer, and its coupling with the flow field can significantly change the macroscopic features of the flow. As radiating flight conditions are typically encountered in re-entry trajectories, the associated flight regimes range from rarefied to continuum, and may have many levels of thermal, chemical and electronic nonequilibrium. Accurate estimates of the nonequilibrium radiation involved in high speed operations such as reentry are essential in order to more efficiently design thermal protection systems.
