Abstract: | In order to interpret and verify the computational model of reaction kinetic for gas explosion in the adiabatic reaction system that the volume and mass were both constant,the system was defined as an ideal reaction system where all the reactions reacted in,and the gas was defined as pure CH4.The methods of numerical analysis,mathematical physical equations and physical chemistry research were used to deduce,detail and verify the computational model of reaction kinetic for gas explosion in constant volume combustion reactor.The solutions of equations set interpreted the variation and situation process of the reaction kinetic for gas explosion in the adiabatic reaction system.Therefore,the computational model of reaction kinetic for gas explosion in the adiabatic reaction system was interpreted and verified. |

Keywords: | constant volume combustion reactor reaction kinetics gas explosion computational model governing equations set |
