Density diffusion in low Mach number flows [PDF]
Journal of Physics: Conference Series, 2022 Abstract In the realm of compressible viscous flow modelling, we briefly revisit the debate on a possible inconsistency of the Navier-Stokes (NS) equations. Then, we recall a recent proposal from the literature, put forward by M. Svärd. One of its features is the mass diffusive term in the continuity equation.

Low-dissipation finite element strategy for low Mach number reacting flows [PDF]
Computers & Fluids, 2020 The present paper extends the conservative finite element convective scheme proposed by Charnyi et al.(Journal of Computational Physics 337, 2017, 289–308) originally formulated for incompressible flows to the low Mach regime. Similar to Lehmkuhl et al.(Journal of Computational Physics 390, 2019, 51–65) stabilisation is only introduced for the ...

The mathematical theory of low Mach number flows [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2005 In this paper one can find a very interesting approach to the mathematical theory of the passage from compressible to incompressible fluid flows as the Mach number tends to zero. Starting from a system of equations which allows to treat simultaneously the three most commonly studied models: the isentropic incompressible Euler equations, the non ...

Coupling strategies for compressible-low Mach number flows [PDF]
Mathematical Models and Methods in Applied Sciences, 2015 In order to enrich the modeling of fluid flows, we investigate in this paper a coupling between two models dedicated to distinct regimes. More precisely, we focus on the influence of the Mach number as the low Mach case is known to induce theoretical and numerical issues in a compressible framework.

Low Mach Number Flows and Combustion [PDF]
SIAM Journal on Mathematical Analysis, 2006 We prove uniform existence results for the full Navier-Stokes equations for time intervals which are independent of the Mach number, the Reynolds number and the P clet number. We consider general equations of state and we give an application for the low Mach number limit combustion problem introduced by Majda.

Artificial compressibility method for strongly anisothermal low Mach number flows [PDF]
Physical Review E, 2021 Artificial compressibility methods aim to reduce the stiffness of the compressible Navier-Stokes equations by artificially decreasing the velocity of acoustic waves in the fluid. This approach has originally been developed as an alternative to the incompressible Navier-Stokes equations as this avoids the resolution of a Poisson equation.
