    Abstract
  • We used high resolution 5th-order WENO (Weighted Essentially Non-Oscillatory) scheme, Level Set method and interface treatment method-RGFM (Real Ghost Fluid Method) in simulating compressible multi-medium flow with high density and high pressure ratio. Simulation of one-dimensional gas-water interaction problem was performed, and the accuracy and reliability of the method was verified. This method is applied to two-dimensional deep water and near free surface explosion simulation. From the simulation results of underwater explosion, it indicates that this method can simulate the shock wave generation, propagation, reflection and transmission after interaction with the interface in underwater explosion. This method is strongly advantageous in simulating compressible multi-medium flow with high density ratio, high pressure ratio and strong discontinuity.
