Sound attenuation in high mach number oscillating bubble media [PDF]
Ultrasonics Sonochemistry, 2023 We study theoretically and numerically sound attenuation in bubble-containing media when the bubbles are freely oscillating at high Mach numbers. This paper expands one of the main forms of bubble-related acoustic damping factors by extending the ...

Mach number dependence of electron heating in high Mach number quasiperpendicular shocks [PDF]
Physics of Plasmas, 2010 The efficiency of electron heating through microinstabilities generated in the transition region of a quasiperpendicular shock for a wide range of Mach numbers is investigated by utilizing particle-in-cell PIC simulation and model analyses.

An Effective AUSM-Type Scheme for Both Cases of Low Mach Number and High Mach Number
Applied Sciences, 2022 A new scheme called AUSMAS (Advection Upstream Splitting Method for All Speeds) is proposed for both high speed and low speed simulation cases. For the cases of low speed, it controls the checkerboard decoupling by keeping the coefficient of the pressure

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 Péclet number.

A low Mach number solver: Enhancing applicability [PDF]
Journal of Computational Physics, 2012 In astrophysics and meteorology there exist numerous situations where flows exhibit small velocities compared to the sound speed. To overcome the stringent timestep restrictions posed by the predominantly used explicit methods for integration in time the Euler (or Navier-Stokes) equations are usually replaced by modified versions.

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.

On a diphasic low Mach number system [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2005 We propose a Diphasic Low Mach Number (DLMN) system for the modelling of diphasic flows without phase change at low Mach number, system which is an extension of the system proposed by Majda in [Center of Pure and Applied Mathematics, Berkeley, report No.

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.
