Low Mach Number Limit for Viscous Compressible Flows
In this survey paper, we are concerned with the zero Mach number limit for compressible viscous flows. For the sake of (mathematical) simplicity, we restrict ourselves to the case of barotropic fluids and we assume that the flow evolves in the whole space or satisfies periodic boundary conditions. We focus on the case of ill-prepared data. Hence highly oscillating acoustic waves are likely to p...
متن کاملComputational Framework for Coupling Compressible and Low Mach Number Codes
A hybrid multicode computational method is developed that allows combining compressible and low Mach number codes into a single computational solver. The proposed methodology can be used for integrated simulations ofmulticomponent engineering problems. Theunsteady couplingbetween the two codes is performedvia exchanging time-dependent state information through the interfaces using overlapping m...
متن کاملCoupling strategies for compressible low Mach number ows
In order to enrich the modelling of uid ows, we investigate in this paper a coupling between two models dedicated to distinct regimes. More precisely, we focus on the in uence of the Mach number as the low Mach case is known to induce theoretical and numerical issues in a compressible framework. A moving interface is introduced to separate a compressible model (Euler with source term) and its l...
متن کاملUnsteady Perturbed Flow at Low Mach Number of a Viscous Compressible Fluid
The problem of the unsteady perturbed two-dimensional flow at low Mach number of a viscous compressible fluid is studied taking the relation between the stress and deformation rates tensors that was obtained and applied in [1] and [3]. It is shown that the system of equations describing the phenomenon is totally hyperbolic and therefore the perturbations in any point P of the field are propagat...
متن کاملA Weakly Asymptotic Preserving Low Mach Number Scheme for the Euler Equations of Gas Dynamics
We propose a low Mach number, Godunov-type finite volume scheme for the numerical solution of the compressible Euler equations of gas dynamics. The scheme combines Klein’s non-stiff/stiff decomposition of the fluxes (J. Comput. Phys. 121:213-237, 1995) with an explicit/implicit time discretization (Cordier et al., J. Comput. Phys. 231:56855704, 2012) for the split fluxes. This results in a scal...
