The Active Flux Scheme on Cartesian Grids and Its Low Mach Number Limit [PDF]
Journal of Scientific Computing, 2019 Finite volume schemes for hyperbolic conservation laws require a numerical intercell flux. In one spatial dimension the numerical flux can be successfully obtained by solving (exactly or approximately) Riemann problems that are introduced at cell interfaces. This is more challenging in multiple spatial dimensions.

Low Mach number limit for viscous compressible flows [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2005 Summary: We are concerned with the zero Mach number limit for compressible viscous flows. For the sake of (mathematical) simplicity, we restrict ourselves to the case of barotropic fluids and we assume that the flow evolves in the whole space or satisfies periodic boundary conditions. We focus on the case of ill-prepared data.

Advances in Nonlinear AnalysisThis article verifies the low Mach number and non-resistive limit of local strong solutions to non-isentropic compressible magnetohydrodynamic (MHD) equations in general three-dimensional bounded domains when the temperature variation is large but finite.

Experimental and Numerical Study of Transonic Cooled Turbine Blades
International Journal of Turbomachinery, Propulsion and Power, 2018 State-of-the-art gas turbines (GT) operate at high temperatures that exceed the endurance limit of the material, and therefore the turbine components are cooled by the air taken from the compressor.

Electronic Journal of Differential Equations, 2019 In this article, we consider the low Mach number limit of the compressible nematic liquid crystal flows in a 3D bounded domain. We establish the uniform estimates with respect to the Mach number for the strong solutions with large initial data in a ...

On the low Mach number limit for 2D Navier–Stokes–Korteweg systems
Mathematics in Engineering, 2022 <abstract><p>This paper addresses the low Mach number limit for two-dimensional Navier–Stokes–Korteweg systems. The primary purpose is to investigate the relevance of the capillarity tensor for the analysis. For the sake of a concise exposition, our considerations focus on the case of the quantum Navier-Stokes (QNS) equations.

Low Mach and Peclet number limit for a model of stellar tachocline and upper radiative zones
Electronic Journal of Differential Equations, 2016 We study a hydrodynamical model describing the motion of internal stellar layers based on compressible Navier-Stokes-Fourier-Poisson system. We suppose that the medium is electrically charged, we include energy exchanges through radiative transfer and

A deep neural network with attention mechanism for flow prediction of compressor blade
Scientific ReportsFor flow-related design optimization problems, computational fluid dynamics (CFD) simulations are commonly used to predict the flow fields. However, the computational expenses of CFD simulations limit the opportunities for design exploration.
