Abstract: |
We present results based on an implementation of the Godunov
Smoothed Particle Hydrodynamics (GSPH). We carry out controlled
hydrodynamical three-dimensional tests, namely the Sod shock tube
and the development of Kelvin-Helmholtz instabilities in a shear
flow test. The results of our tests demonstrate GSPH provides a
much improved description of contact discontinuities, with respect
to SPH, and is able to follow the development of gas-dynamical
instabilities, such as the Kevin–Helmholtz and the Rayleigh-Taylor
ones. |
