Abstract
A mathematical model of the combustion process of methane hydrate in a closed volume is presented, taking into account the kinetics of its decomposition (nonequilibrium), as well as absorption of thermal radiation energy. Based on the numerical solution by the large particle method, the distributions of the main parameters of the system were constructed. The authors compare the specific features of hydrate combustion for cases corresponding to different values of the fraction of evaporated water released during hydrate dissociation. It is shown that partial evaporation of water formed during decomposition of the hydrate leads to an increase in the combustion temperature of the gas mixture and to more intense decomposition of the hydrate compared to the case of complete evaporation of all released water. The dependences of the flame temperature, the maximum pressure of the gas mixture, and the law of motion of the phase transition front on the degree of evaporation of the released water are constructed and analyzed.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
