Application of front tracking to two-dimensional gas dynamics calculations
Abstract
The results from some validation tests for a two-dimensional front tracking code for gas dynamics are presented. Initial value problems with circularly symmetric initial data are studied, and the results are compared to those obtained by a one-dimensional calculation exploiting the circular symmetry. The Kelvin-Helmholtz instability in the compressible, small amplitude regime is also studied, and the results are compared with a linear perturbation analysis. Results from a large amplitude calculation are included, showing vortex formation and roll-up.
