SPH Simulation of Rayleigh-Taylor Instability

Rayleigh-Taylor instability of fluid interface was simulated by the smoothed particle Hydrodynamics(SPH) method. The growth of the interface instability was presented, and the fungus appearance of the instability was obtained. The characters showed by the numerical results indicate that the numerical results are logical, and the SPH method has the potential to simulate Rayleigh-Taylor instability.
