Abstract
A high-resolution multi-fluid parabolic piecewise method (MFPPM) ispresented to simulate the Richtmyer–Meshkov (RM) instability instratified cylindrical shells. However, the algorithm captures do nottrack the interfaces between distinct large deformation materials. Toreach verification and validation of our MFPPM code, we select twoexperimental models for simulations, one is from the Lawrence LivermoreNational Laboratory, and the other is from our Laboratory for ShockWave and Detonation Physics. The former result is in excellentagreement with the experiment and the Couple Arbitrary Lagrange–Euler(CALE) code, the latter is in general consistent with our experiment.It is found that the MFPPM code is reasonably successful in simulatingmany aspects of the gelatin-ring RM experiments.
