On the Low Mach Number Limit for Quantum Navier--Stokes Equations [PDF]
SIAM Journal on Mathematical Analysis, 2020 We investigate the low Mach number limit for the 3-D quantum Navier-Stokes system. For general ill-prepared initial data, we prove strong convergence of finite energy weak solutions to weak solutions of the incompressible Navier-Stokes equations. Our approach relies on a quite accurate dispersive analysis for the acoustic part, governed by the well ...

Low Mach number limit for the quantum hydrodynamics system [PDF]
Research in the Mathematical Sciences, 2016 In this paper we deal with the low Mach number limit for the system of quantum-hydrodynamics, far from the vortex nucleation regime. More precisely, in the framework of a periodic domain and ill-prepared initial data we prove strong convergence of the solutions towards regular solutions of the incompressible Euler system.

Low Mach number limit on thin domains [PDF]
Nonlinearity, 2020 Abstract We consider the compressible Navier–Stokes system describing the motion of a viscous fluid confined to a straight layer . We show that the weak solutions in the 3D domain converge strongly to the solution of the 2D incompressible Navier–Stokes equations (Euler ...

On the Low Mach Number Limit for the Compressible Euler System [PDF]
SIAM Journal on Mathematical Analysis, 2019 In this paper, we propose a new approach to singular limits of inviscid fluid flows based on the concept of dissipative measure-valued solutions. We show that dissipative measure-valued solutions of the compressible Euler equations converge to the smooth solution of the incompressible Euler system when the Mach number tends to zero. This holds both for

Turbulence in the near scrape-off layer towards the L-mode density limit in ASDEX-Upgrade
Nuclear Materials and Energy, 2022 The L-mode density limit in ASDEX Upgrade is investigated with focus on the scrape-off layer. We observe a chain of events that involves the collapse of the E×B outer shear layer (just outside the separatrix), widening of the electron pressure fall-off ...

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.
