The Supercomputing Simulation of Instability and Shock Waves in Gas Giant

Abstract

The research of the gas giant atmosphere behavior during its interaction with a stellar wind is given in paper. The various case of interaction of atmosphere with the dense gas current are considered. The numerical model based on gravitational hydrodynamics equations was used. The combination of operator splitting approach, Godunov’s and HLL methods, and the piecewise parabolic method on local stencil is used for the solution of equations. The computing experiments were made on the supercomputer equipped with Intel Xeon Phi accelerators.
