Low Mach Number Limit of the Full Navier-Stokes Equations [PDF]
Archive for Rational Mechanics and Analysis, 2005 The low Mach number limit for classical solutions to the full Navier Stokes equations is here studied. The combined effects of large temperature variations and thermal conduction are accounted. In particular we consider general initial data. The equations leads to a singular problem, depending on a small scaling parameter, whose linearized is not ...

Low Mach number limit of multidimensional steady flows on the airfoil problem [PDF]
Calculus of Variations and Partial Differential Equations, 2020 In this paper, we justify the low Mach number limit of the steady irrotational Euler flows for the airfoil problem, which is the first result for the low Mach number limit of the steady Euler flows in an exterior domain. The uniform estimates on the compressibility parameter $\varepsilon$, which is singular for the flows, are established via a ...

ESAIM: Proceedings and Surveys, 2017 This paper provides the full proof of the results announced by the authors in [C. R. Acad. Sciences (2016)]. We introduce an original relative entropy for compressible Navier-Stokes equations with density dependent viscosities and discuss some possible ...

Stability with respect to domain of the low Mach number limit of compressible heat-conducting viscous fluid [PDF]
, 2022 We investigate the asymptotic limit of solutions to the Navier-Stokes-Fourier system with the Mach number proportional to a small parameter $\varepsilon \to 0$, the Froude number proportional to $\sqrt{\varepsilon}$ and when the fluid occupies large ...

Modelling of phase transitions in granular flows
ESAIM: Proceedings and Surveys, 2017 We present in this work a system for unidimensional granular flows first mentioned in a paper of A. Lefebvre–Lepot and B. Maury (2011), which captures the transitions between compressible and incompressible phases.

Low Mach number limit for the multi-dimensional full magnetohydrodynamic equations [PDF]
Nonlinearity, 2012 The low Mach number limit for the multi-dimensional full magnetohydrodynamic equations, in which the effect of thermal conduction is taken into account, is rigorously justified in the framework of classical solutions with small density and temperature variations.

An example of low Mach (Froude) number effects for compressible flows with nonconstant density (height) limit [PDF]
, 2005 International audienceThe purpose of this work is to study an example of low Mach (Froude) number limit of compressible flows. This allows us to connect the viscous shallow water equation and the viscous lake equations.

A low-Mach Roe-type solver for the Euler equations allowing for gravity source terms *
ESAIM: Proceedings and Surveys, 2017 In order to perform simulations of low Mach number flow in presence of gravity the technique from [23] is found insufficient as it is unable to cope with the presence of a hydrostatic equilibrium.

The Effect of Chemical Reactivity on the Formation of Gaseous Oblique Detonation Waves
Aerospace, 2019 High-fidelity numerical simulations using a Graphics Processing Unit (GPU)-based solver are performed to investigate oblique detonations induced by a two-dimensional, semi-infinite wedge using an idealized model with the reactive Euler equations coupled ...
