Book excerpt: A closed-form equation is derived for stagnation point reentry radiative heat transfer accounting for the combined effects of radiative cooling and nongray self-absorption within the shock layer. The equation can be applied for both continuum and atomic line radiation. In addition, the equation is shown to agree favorably with existing numerical data for stagnation point, continuum radiative heat transfer for a wide variety of conditions. Also, the equation is shown to apply to the end-wall radiative heat transfer behind a strong reflected shock wave in a shock tube. Finally, the equation provides a rapid means of obtaining, by hand, reasonably accurate engineering estimates for reentry radiative heat transfer including shock layer radiative cooling and nongray self-absorption.
