Abstract

A mathematical model for calculation of gasdynamics, which models to a first approximation the process of fighting a fire inside a channel of arbitrary geometry by a pinpoint explosion, is proposed. The main factors determining the parameters of the process have been revealed. The formulas to determine the maximum shift of the region occupied by a hot gas relative to its initial position as well as the formulas for the maximum temperatures throughout the process and along the length of the channel at the moment of establishment of the “quasistationary” position of this region have been obtained by generalization of the data of a numerical experiment. It is shown that the geometry of the channel has a substantial influence on the dynamics of the process.
