Verification and Validation of CFD Modeling for Low-Flow-Coefficient Centrifugal Compressor Stages
Energies, 2021 In this paper, the numerical model of a centrifugal compressor low-flow stage is verified. The gaps and labyrinth seals were simulated in the numerical model. The task was to determine the optimal settings for high-quality modeling of the low-flow stages.

High order semi-implicit weighted compact nonlinear scheme for the all-Mach isentropic Euler system
Advances in Aerodynamics, 2020 The computation of compressible flows at all Mach numbers is a very challenging problem. An efficient numerical method for solving this problem needs to have shock-capturing capability in the high Mach number regime, while it can deal with stiffness and ...

A Massively Parallel Hybrid Finite Volume/Finite Element Scheme for Computational Fluid Dynamics
Mathematics, 2021 In this paper, we propose a novel family of semi-implicit hybrid finite volume/finite element schemes for computational fluid dynamics (CFD), in particular for the approximate solution of the incompressible and compressible Navier-Stokes equations, as ...

Low Mach Number Limit of Viscous Compressible Magnetohydrodynamic Flows [PDF]
SIAM Journal on Mathematical Analysis, 2009 The relationship between the compressible magnetohydrodynamic flows with low Mach number and the incompressible magnetohydrodynamic flows is investigated. More precisely, the convergence of weak solutions of the compressible isentropic viscous magnetohydrodynamic equations to the weak solutions of the incompressible viscous magnetohydrodynamic ...

Low Mach Number Limit of the Full Navier-Stokes Equations [PDF]
Archive for Rational Mechanics and Analysis, 2005 The low Mach number limit for classical solutions to the full Navier Stokes equations is here studied. The combined effects of large temperature variations and thermal conduction are accounted. In particular we consider general initial data. The equations leads to a singular problem, depending on a small scaling parameter, whose linearized is not ...

Low Mach number limit of multidimensional steady flows on the airfoil problem [PDF]
Calculus of Variations and Partial Differential Equations, 2020 In this paper, we justify the low Mach number limit of the steady irrotational Euler flows for the airfoil problem, which is the first result for the low Mach number limit of the steady Euler flows in an exterior domain. The uniform estimates on the compressibility parameter $\varepsilon$, which is singular for the flows, are established via a ...
