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. In the model analyses saturation levels of effective electron temperature as a result of microinstabilities are

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.

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. We consider general equations of state and we give an application for the low Mach number limit combustion problem introduced by Majda.

On a diphasic low mach number system [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2005 The author proposes a diphasic low Mach number (DLMN) system for the modelling of diphasic flows at low Mach number. This system filters out the acoustic waves but keeps all the informations coming from the thermodynamic as the equations of state and the entropy contrary to a standard incompressible diphasic Navier-Stokes system.

Accounting for convective effects in zero-Mach-number thermoacoustic models [PDF]
, 2014 This paper presents a methodology to account for some mean-flow effects on thermo-acoustic instabilities when using the zero-Mach-number assumption. It is shown that when a computational domain is represented under the M=0 assumption, a nonzero-Mach ...

Low Mach Asymptotic Preserving Scheme for the Euler-Korteweg Model [PDF]
, 2013 We present an all speed scheme for the Euler-Korteweg model. We study a semi-implicit time-discretisation which treats the terms, which are stiff for low Mach numbers, implicitly and thereby avoids a dependence of the timestep restriction on the Mach ...

Fuzzy-based prediction for suddenly expanded axisymmetric nozzle flows with microjets [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2022 The current research focuses on the implementation of the fuzzy logic approach for the prediction of base pressure as a function of the input parameters.
