Abstract

Purpose. To develop a mathematical model for estimating the configuration factor, which takes into account the triangular shape of the radiating surface and the mutual positional relationship relative to the receiving surface.

Methods. The development of equations for determining the configuration factor was based on the results of the analysis of experimental studies and existing approaches to determining the magnitude of fire gaps between buildings and structures, and Lambert's law for determining the amount of energy transmitted from the radiation to the receiving surface.

Findings. For parallel radiating and receiving surfaces, located arbitrarily relative to each other, the analytical expression is obtained that allows determining the configuration factor of an element of receiving surface by emitting surface which have the shape of an arbitrary convex polygon.

Application field of research. Determination of the fire breaks between buildings, taking into account the individual characteristics of the objects calculated – gabled roof made of combustible materials.
