title = "Numerical simulation of gas deflagration and venting in cylindrical vessel",
abstract = "Gas explosion accident in cylindrical vessel frequently happens in plants, which severely threatens safety production of process industries. To prevent such accidents appropriately sized emergency vent is installed. Sizing the vent is most important which requires fully understanding of gas deflagration and venting process in cylindrical vessel. In this paper, physical model is presented first after well investigation of deflagration and venting process in cylindrical vessel. Then a mathematical model is built based on law of energy and mass conversation, gas state equation, isentropic compression equation and mass rate of discharging equation. By four rank Runge-Kutta method the differential equations are solved. Pressure, rate of pressure rise, distance of flame front from ignition point and flame speed at different time can be calculated. Numerical simulation results show that vent area and vent opening pressure have dramatic influence on gas deflagration and venting in vessel.",
