The level set method, TVD scheme of second order upwind procedure coupled with flux limiter, ENO velocity extension procedure inside the bubble, and MAC projection algorithm were incorporated to simulate the whole collapse evolution of a cavitation bubble near a rigid wall with many complicated phenomena, such as topology distortion and shrinking, jet impact, bubble breaking into a toroidal form, and diminishing volume to zero, etc.The bubble shape, evolution and distribution of velocity and pressure fields of the fluid during the bubble collapsing were investigated.It is found that the method is numerically stable and has good convergence property, and the results are in good agreements with those in previous work.
