On the basis of multi-fluid volume fraction (VOF) and piecewise parabolic method (PPM), a multi-fluid hydrodynamic program MFPPM (Multi-Fluid Piecewise Parabolic Method) was developed and performed to study the Richtmyer-Meshkov instability of gas/liquid interface. The influences of initial perturbations and grids on the fluid mixing zone (FMZ) were mainly researched when it is accelerated by shock waves, and the FMZ width, bubble and spike height growing with time were presented simultaneously. By comparing the computational results, it shows that the initial perturbations affect the FMZ growth rate extremely, especially at late times. The evolution of spike is similar to the FMZ, the bubble height increases linearly with time basically, and influenced little by initial perturbations, but the configuration is quite different, and as the effect of grid size is.
