โฆ Synopsis
A unified method for computing incompressible and compressible flows with Mach-uniform accuracy and efficiency is described. The method is equally applicable to stationary and nonstationary flows. A pressure-based discretisation on a staggered grid in general boundary-fitted coordinates is used for the Euler equations. Extension to Navier-Stokes is straightforward. Dimensionless variables that remain finite for all Mach numbers are used. Mach number independent accuracy and efficiency is shown by numerical experiments.

A new numerical approach based on consistent operator splitting is presented for computing compressible, highly stratified flows in astrophysics. The algorithm is particularly designed to search for steady or almost steady solutions for the time-dependent Navier -Stokes equations, describing viscous
We propose a numerical method for modeling two-phase flow consisting of separate compressible and incompressible regions. This is of interest, for example, when the combustion of fuel droplets or the shock-induced mixing of liquids is numerically modeled. We use the level set method to track the int
