Mach Number Dependence of Electron Heating in High Mach Number Quasiperpendicular Shocks [PDF]
Physics of Plasmas, 2010 Efficiency of electron heating through microinstabilities generated in the transition region of a quasi-perpendicular shock for wide ange of Mach numbers is investigated by utilizing PIC (Particle-In-Cell) simulation and model analyses.

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.

Low Mach number effect in simulation of high Mach number flow [PDF]
, 2012 In this note, we relate the two well-known difficulties of Godunov schemes: the carbuncle phenomena in simulating high Mach number flow, and the inaccurate pressure profile in simulating low Mach number flow.

Low Mach Number Fluctuating Hydrodynamics for Electrolytes
Physical Review Fluids, 2016 We formulate and study computationally the low Mach number fluctuating hydrodynamic equations for electrolyte solutions. We are interested in studying transport in mixtures of charged species at the mesoscale, down to scales below the Debye length, where

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.

Exploring the spectral properties of radio relics – I: integrated spectral index and Mach number [PDF]
, 2021 Radio relics are the manifestation of electrons presumably being shock (re-)accelerated to high energies in the outskirts of galaxy clusters. However, estimates of the shocks’ strength yield different results when measured with radio or X-ray ...

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.
