Computation of three dimensional Rayleigh-Taylor instability in compressible
fluids is performed on a MIMD computer. In this paper we will present our study using
two numerical methods, the front tracking method and the level set method. We will discuss algorithms used in the 3D front tracking method and parallel implementation using this method. This includes 3D interface partition, unstructured grid generation and parallel coordination of the program. Our algorithms using level set method include application of a second order TVD scheme with a full parallelization to the 3D Euler equations. The computational program will be used for a 3D study of bubble evolution in the Rayleigh-Taylor instability and for large scale simulation of a 3D random fluid interface. The objective of his research is to compare the numerical solutions with the experimental results by Taylor and Youngs.
