Quasiperpendicular High Mach Number Shocks [PDF]
Physical Review Letters, 2015 Shock waves exist throughout the universe and are fundamental to understanding the nature of collisionless plasmas. Reformation is a process, driven by microphysics, which typically occurs at high Mach number supercritical shocks. While ongoing studies have investigated this process extensively both theoretically and via simulations, their observations

Low Mach Number Modeling of Type Ia Supernovae [PDF]
Astrophys.J.637:922-936,2006, 2005 We introduce a low Mach number equation set for the large-scale numerical simulation of carbon-oxygen white dwarfs experiencing a thermonuclear deflagration. Since most of the interesting physics in a Type Ia supernova transpires at Mach numbers from 0.01 to 0.1, such an approach enables both a considerable increase in accuracy and savings in computer ...

A minicourse on the low Mach number limit
Discrete & 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.

Mach number study of supersonic turbulence: The properties of the density field [PDF]
, 2015 We model driven, compressible, isothermal, turbulence with Mach numbers ranging from the subsonic ($\mathcal{M} \approx 0.65$) to the highly supersonic regime ($\mathcal{M}\approx 16 $). The forcing scheme consists both solenoidal (transverse) and compressive (longitudinal) modes in equal parts.

An all Mach number finite volume method for isentropic two-phase flow [PDF]
J. Num. Math., 2022 We present an implicit–explicit finite volume scheme for isentropic two phase flow in all Mach number regimes. The underlying model belongs to the class of symmetric hyperbolic thermodynamically compatible models.

Novel Characteristics of Subsonic Coflowing Jets With Varying Lip Thickness [PDF]
Journal of Aerospace Technology and Management, 2020 Effect of Mach number on coflowing jet at lip thickness of 0.2 Dp, 1.0 Dp and 1.5 Dp (where Dp is primary nozzle exit diameter, 10 mm) at Mach numbers 1.0, 0.8 and 0.6 were studied experimentally.

Mach and Froude Numbers on Mars [PDF]
The Planetary Science Journal, 2022 Abstract Mars atmospheric global circulation models exhibit transonic jet streaks during northern winter, which motivates this study of the Mach number, Ma (the ratio of flow speed to the speed of sound), and Froude number, Fr (the ratio of flow speed to the speed of buoyancy waves), as a function of season and location.

A homogeneous relaxation low mach number model [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2021 In the present paper, we investigate a new homogeneous relaxation model describing the behaviour of a two-phase fluid flow in a low Mach number regime, which can be obtained as a low Mach number approximation of the well-known HRM. For this specific model, we derive an equation of state to describe the thermodynamics of the two-phase fluid.
