The paper deals with mathematical modelling of the process of an explosion of a cloud of reactive gases and its impact on the environment. The research may be relevant to ensure fire safety and to prevent explosion hazards at industrial production facilities that use reactive gas mixtures as a working medium and at high-pressure industrial pipelines used for their transportation. The goal of the study is to develop and test a computational technology for numerical modelling of clouds of reactive gas mixture expansions and loads evaluation. To describe the chemical processes in the explosion, a simplified mathematical model is proposed which based on the assumption of frozen chemical reactions. Using the model, a set of User Defined unctions is implemented in ANSYS Fluent and applied for solving a problem of a “propylene-air” cloud explosion inside the T-shape tube with two closed and one open ends.
