Intense destruction of bodies of laminar or granular structure in hypersonic flow
Abstract
The paper deals with a material granular or laminar structure, composed of alternating radiation transmitting and nontransmitting zones. An expression for the heat exchange efficiency of the material is derived, and the nature of the destruction of the body in a stagnation air flow is examined under the assumption of an optically thin boundary layer. The case of intense destruction, where the convective heat flux to the wall is zero and destruction occurs only under the action of radiant flux, is analyzed. An approximate analytical solution of the fluid film's equations of motion is obtained. The liquid and gas phase solutions lead to a system of transcendental equations for the destruction problem.
