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 ...

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

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.

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.

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 ...
