Three-Dimensional Formulation of the Radiant Heat Flux Variation on a Cylinder Engulfed in Flames

Abstract

A three-dimensional formulation is used to determine the incident radiant heat flux on a cylinder surface which is engulfed in flames. For an axisymmetric horizontal pool fire of a specified flame shape, effective flame radiation temperature and a gray flame absorption coefficient, this analysis computes the variation of the incident radiant heat flux along the length and around the circumference of the tank portrayed as a cylinder, engulfed in flames. The radiant flux density from the flame to the cylinder becomes maximum toward the center of the pool and decreases markedly toward the edges. The points which are receiving the maximum amount of radiation heat flux around the circumference of the cylinder are also determined.
