4696 – Heat Transfer through a Composite Wall with a Rectangular Graybody Radiating Cavity: A Numerical Solution PDF

A numerical finite-difference analysis is developed in this paper for steady-state heat transfer in a composite wall with a two-dimensional rectangular graybody radiating cavity with and without natural convection circulation of air. The primary objective of this paper is to provide a clear and systematic approach that can be used to accurately account for the effects of radiation in practical applications of this type and to establish a basis for evaluating the error of the first-order two-dimensional method.
