Measure-Valued Low Mach Number Limits of Ideal Fluids
SIAM Journal on Mathematical Analysis, 2023 As a framework for handling low Mach number limits we consider a notion of measure-valued solution of the incompressible Euler system which explicitly formulates the usually suppressed dependence on the pressure variable. We clarify in which sense such a measure-valued solution is generated as a low Mach limit and state sufficient conditions for this ...

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 ...

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.

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 ...

A minicourse on the low Mach number limit
Discrete and Continuous Dynamical Systems - S, 2008 These lectures are devoted to the study of the low Mach number limit for classical solutions of the compressible Navier-Stokes or Euler equations for non-isentropic fluids. We study the general case where the combined effects of large temperature variations and thermal conduction are taken into account.

Influence of flow parameters on cavity-tone control using a rear-wall protrusion [PDF]
AIP AdvancesThis study investigated the effects of flow parameters on cavity-tone suppression using a rear-wall protrusion, which is a passive control device previously optimized for low-Mach-number conditions. Three key nondimensional parameters were systematically
