MAESTROeX: A Massively Parallel Low Mach Number Astrophysical Solver [PDF]
Journal of Open Source Software, 2019 We present MAESTROeX, a massively parallel solver for low Mach number astrophysical flows. The underlying low Mach number equation set allows for efficient, long-time integration for highly subsonic flows compared to compressible approaches. MAESTROeX is

Low Mach number limit on thin domains [PDF]
Nonlinearity, 2020 We consider the compressible Navier-Stokes system describing the motion of a viscous fluid confined to a straight layer $ _ =(0, )\times\mathbb{R}^2$. We show that the weak solutions in the 3D domain converge strongly to the solution of the 2D incompressible Navier-Stokes equations (Euler equations) when the Mach number $ $ tends to zero as well as

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.

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.

Aeroengine High-Attitude/Low Mach Number Oscillations: Mechanism and Prevention Design
International Journal of Aerospace Engineering, 2021 The issue of aeroengine oscillations over high-attitude and low-speed flight envelope has been an unsolved problem due to their classified nature and hard reproduction in simulated altitude test stand.

Low Mach number limit of some staggered schemes for compressible barotropic flows [PDF]
Mathematics of Computation, 2018 In this paper, we study the behaviour at low Mach number of numerical schemes based on staggered discretizations for the barotropic Navier-Stokes equations.

An all Mach number relaxation upwind scheme
, 2020 The present paper concerns the derivation of finite volume methods to approximate the weak solutions of the Euler equations within all Mach number regimes. To address such an issue, we develop a Suliciu relaxation type scheme.

Flutter analysis of tapered composite fins: Analysis and experiment [PDF]
FME Transactions, 2022 In the present work, the aeroelastic stability of tapered composite plates is investigated. Existing flutter models, based on the typical section approach, are reviewed for quasi-steady and unsteady low Mach number axial flows and modified for the thin ...
