Modeling of the combustion process of methane hydrate taking into account the kinetics of the decomposition process
Abstract This paper presents a mathematical model of the combustion process of methane gas hydrate in a closed volume, taking into account the kinetics of its decomposition. The system of basic equations, which includes the equations of conservation of mass (for the entire mixture of gases and each...
