Abstract

There was made numerical comparison of integration methods for calculation of angular coefficients (ACs) with the aid of integration under different relative position of surfaces. There was offered a simple criterion for assessment of computational error of ACs at first glance, as well as algorithm of a priory choice of method and number of integration nodes before computation of ACs. The algorithm allows substantially decrease time of computation of ACs by means of use of minimum number of nodes for each pair of surface zones. The proposed algorithm is applied for analysis of continuous furnace geometry.
