STUDY OF 3-DIMENSIONAL RAYLEIGH-TAYLOR INSTABILITY IN COMPRESSIBLE FLUIDS THROUGH LEVEL SET METHOD AND PARALLEL COMPUTATION

Computation of three-dimensional (3-D) Rayleigh-Taylor instability in compressible fluids is performed on a MIMD computer. A second-order TVD scheme is applied with a fully parallelized algorithm to the 3-D Euler equations. The computational program is implemented for a 3-D study of bubble evolution in the Rayleigh-Taylor instability with varying bubble aspect ratio and for large-scale simulation of a 3-D random fluid interface. The numerical solution is compared with the experimental results by Taylor.
