Effect of Thermal Conductivity on the Knudsen Layer at Ablative Surfaces (Postprint)

Abstract

In this paper we develop an analytical model of Knudsen layer at the ablative wall taking into account the temperature gradient in the bulk gas. The region of validity of the existing models and effect of the temperature gradient on the Knudsen layer properties are calculated.
