Level Set interface treatment and its application in Euler method

Level Set interface treatment method is introduced into Euler method, which is employed for interface treatment method for multi-materials. Combined with the ghost fluid method, the moving interface is tracked. Fifth-order WENO spatial discretization and third-order TVD Runge-Kutta time discretization methods are used. Shock-wave action on bubble, implosion and velocity field Shock effect bubbles; implosion and velocity field are simulated by means of LS-MMIC3D programmed by C++. Numerical results show that the Level Set interface treatment method is effective and feasible for multi-material interface treatment in comparison with the WENO method.
