A MODIFICATION OF LEVEL SET RE-INITIALIZED METHOD FOR THE SHOCK WAVES THROUGH THE AIR BUBBLE

ABSTRACT
For the re-initialization problem of the level set method, a new re-initialization formula of smoothing parameter based on the traditional implicit method is proposed. The improved method is applied to describe the process of the shock through the air bubble by means of numerical simulation. Numerical results show that the method is superior to the traditional level set method.
