Numerical Simulation on Actuation Process of An Small Explosively Actuated Valve

According to the composition and actuation process of the small explosively actuated valve,a numerical model which accounts for squib pressure-dependent combustion,tube cutting and squeeze sealing between the pistion and valve bore was presented.The experimental results show that the simulation outputs of the model and experimental results match well,the model can be used for the research of the actuation process of the explosively actuated valve.
