Radiant heat transfer at high temperatures
Abstract
The majority of methods of the radiant heat transfer theory is based on certain simplified assumptions of radiation properties. Approximate methods for the determination of radiant heat transfer at high temperatures are considered, giving attention to the thin-layer approximation, the 'gray' gas approximation, the radiant heat conduction approximation, the zonal method, and methods taking into account the frequency dependence of radiation properties. The problem of similarity is discussed along with questions concerning combined heat transfer, radiative and convective heat transfer involving a hypersonic flow over a blunt body, aspects of local equilibrium disturbance, and nonequilibrium phenomena associated with a hypersonic flow streamlining a blunt body.
