一种超高速发射实验装置的改进及其数值模拟
An Improved of Experimental Hypervelocity Launcher and Simulation
摘要
Abstract
A numerical simulation method for calculation of the three-stage light-gas gun impacts on launch flier to hypervelocity is presented.Based on multi-fluid volume of fraction(VOF) and parabolic piecewise method(PPM),a multi-fluid parabolic piecewise method(MFPPM) shock wave physics code is developed to calculate the experimental hypervelocity launchers.To verify and validate our code of MFPPM,some experimental hypervelocity launchers from Sandia National Laboratories are simulated,and the numerical results of flier velocity are excellent in agreement with that experiment(the maximal relative error is 1.07%).Experiment and simulation results of our experiment on the three-stage light-gas gun are given(the maximal relative error is 1.04%).To satisfy well of the high-pressure equation of state(EOS) data measurement,an improved design model from the computation is presented.关键词
