The mathematical model of the pressure field in the vented explosion process in closed cylindrical vessel containing methane and ethane was built based on the soft-ware fluent. The characteristics of pressure development, flame propagation, gas flow and flammable gas concentration change have been studied in the process of bursting disc open to pressure completely discharge. The results show that the development and change of vessel pressure exhibit different characteristics in the venting explosion process of different flammable gas, and vessel pressure will take on a double-peak phenomenon during the explosion process of highly reactive gas. The turbulent flow produced in the process of venting explosion will elongate the flame along the vessel surface near vent and enhance the burning rate.
