APPROXIMATE ANALYTICAL METHODS IN THE THEORY OF RADIATIVE HEAT TRANSFER IN AN ABSORBING MEDIUM,

This article is concerned with the solution of the problem of radiative heat transfer in a radiating system consisting of a finite number n of uniform and isothermal gray bodies located on the boundary of the system and separated by an absorbing medium consisting of a finite number m of uniform, partially transparent, constant temperature regions zones. This solution, representing the conclusion of a solving system of algebraic equations for the generazed solving scope of radiation, is the basis for the development of a zonal method to calculate radiative heat transfer in different radiating systems and, in particular, in fire boxes and industrial flame furnaces, and also for a theoretical basis for experimental methods of investigating the processes of radiative heat transfer, connected with the application of both thermal and light modeling of the stated processes.
