Dynamic Prediction and Measurement of Overpressure for Venting of Gas Explosion

Abstract:

In order to predict the effects of gas volume and mass inertia of explosion doors on overpressure for venting of gas explosion, a numerical method are used to simulate some situations of venting devices such as panels or explosion doors. The numerical data are in good agreement with the experiments of panels given an overpressure peak. A set of experiments were carried out in a 10 m3 silo and methane is used as fuel. The results of measurement in experiments indicated that the inertial mass of explosion door has a possibility of causing considerable damage and has effected on the rate of opening vented door and the pressure rise in such the experimental silo.
