At present, the process of heat transfer as a possible criterion for determining the fire distances between buildings is insufficiently studied. In this regard, to justify the value of the fire distance between buildings, one of the possible options is to create an appropriate mathematical model. On the basis of gas dynamics methods, a mathematical model of the processes of the thermal effect of a fire through the window opening of a building with a combustible facade on the elements of adjacent objects has been developed. It is shown that its solution can be implemented in the FDS software package with acceptable convergence in comparison with experimental studies. It was found that the data of mathematical modeling are as close as possible to the averaged data of the experiment. Dependences of temperature changes on the time of fire exposure on samples and distance from the source of heat exposure were determined. The obtained data can be used to substantiate fire-prevention distances between buildings and structures due to the mathematical model of heat transfer between objects during a fire using gas dynamics methods, as well as during the substantiation of the algorithm for creating a mathematical model.
