Abstract

The authors describe the calculation of the external heat transfer in the furnaces of tubular ovens of box type, based on numerical solution of systems of integro-differential equations of radiative gasdynamics using the K-E turbulance model and an empirical combustion model. Radiative heat transfer is considered in the S2 approximation of the method of discrete ordinates, and the SIMPLE algorithm is used to solve the gasdynamic part of the problem. The influence of furnace width on the external heat transfer was investigated numerically.
