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 ...

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.

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.

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.

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

Sonic Eddy Model of the Turbulent Boundary Layer
Fluids, 2022 The effects of Mach number on the skin friction and velocity fluctuations of the turbulent boundary layer are considered through a sonic eddy model. Originally proposed for free shear flows, the model assumes that the eddies responsible for momentum ...
