HARDENING TECHNOLOGY STUDIES - II. BASE - RADS. A FORTRAN PROGRAM FOR RADIATION ATTENUATION IN THE NEAR WAKE.

Abstract

Radiation attenuation in the near turbulent wake for cone vehicles in the presence of an external radiation source is considered. The wake is characterized employing a two-dimensional flow model accounting for the upstream developed boundary layer and mass addition from the base. Radiation from a spherical external source to any position on the base is evaluated considering non-grey absorption in an isothermal constant pressure wake containing the equilibrium species composition associated with sublimation of the base ablator. A computer program, BASE-RADS, for evaluating the coupled wake flow field, attenuated base radiation, and ablator response is described. Application of the program is illustrated for an example encounter situation and base material. (Author)
