Low Mach number instability of an explicit numerical scheme
A low Mach number instability occurs in a scheme for the solution of gas dynamics and multiphase flow problems. The report illustrates the instability and explains its origin, using a simplified Von Neumann stability analysis. Finally, a simple modification to the scheme, which completely eliminates the instability, is presented.
