Abstract [en]

Sixth-order compact and non-compact filter schemes that were designed for multiscale Navier-Stokes, and ideal and non-ideal magnetohydrodynam-ics (MHD) systems are employed to simulate a 2-D Rightmyer-Meshkov instability (RMI). The suppression of this RMI in the presence of a magnetic field was investigated by Samtaney (2003) and Wheatley et al. (2005). Numerical results illustrated here exhibit behavior similar to the work of Samtaney. Due to the different amounts and different types of numerical dissipations contained in each scheme, the structures and the growth of eddies for this chaotic-like inviscid gas dynamics RMI case are highly grid size and scheme dependent, even with many levels of refinement.
