UNSTEADY CONJUGATE PROBLEM OF RADIATIVE-CONVECTIVE HEAT TRANSFER IN A LAMINAR BOUNDARY LAYER ON A THIN PLATE

Abstract

Unsteady radiative convective heal transfer between a thin thermally insulated plate and laminar homogeneous flows of gray emitting, absorbing, and scattering mediums is investigated numerically for a one-dimensional radiation model. The effect of scattering anisotropy, reflection from the plate surface, and optical thickness in monotonous and nonmonolonous temperature fields of the boundary layer on heat transfer is revealed qualitatively in the context of the approximate model. The significant effect of radiation on temperature formation in a streamlined body confirms the necessity for an accurate account of the radiative heal transfer component in calculations of conjugate problems
