Preferential Concentration of Particles in Forced Turbulent Flows: Effects of Gravity
Energies, 2023 The impact of gravity on the particle preferential concentration is investigated by direct numerical simulations in an Eulerian–Lagrangian framework for a large range of Stokes numbers Stη=0.01∼4. For particles with small Stokes numbers such as Stη=0.01,

Heat Transfer in a Non-Isothermal Collisionless Turbulent Particle-Laden Flow
Fluids, 2022 To better understand the role of particle inertia on the heat transfer in the presence of a thermal inhomogeneity, Eulerian–Lagrangian direct numerical simulations (DNSs) have been carried out by using the point–particle model.

The Stokes-Einstein relation at moderate Schmidt number [PDF]
The Journal of Chemical Physics, 2013 The Stokes-Einstein relation for the self-diffusion coefficient of a spherical particle suspended in an incompressible fluid is an asymptotic result in the limit of large Schmidt number, that is, when momentum diffuses much faster than the particle.

Study on the Erosion Characteristics of Non-spherical Particles in Liquid-solid Two-phase Flow [PDF]
Journal of Applied Fluid Mechanics, 2023 Elbow erosion, defined as wall thinning due to the continuous interactions between solid particles and surface, is a common phenomenon in catalyst addition/withdrawal pipeline systems used in residual oil hydrogenation units.

Marking function of Stokes number on airfoils’ aerodynamic penalties in a gas–solid flow
IET Renewable Power Generation, 2021 This paper aims to employ the Stokes number to mark aerodynamic penalties of airfoils caused by particles, which is crucial to implement their scaling experiments in a gas‐solid flow.

On the Reynolds number expansion for the Navier–Stokes equations [PDF]
Nonlinear Analysis: Theory, Methods & Applications, 2014 In a previous paper of ours [Nonlinear Anal. 2012] we have considered the incompressible Navier-Stokes (NS) equations on a d-dimensional torus T^d, in the functional setting of the Sobolev spaces H^n(T^d) of divergence free, zero mean vector fields (n > d/2+1).

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 ...

Dynamic mode decomposition of inertial particle caustics in Taylor–Green flow
Scientific Reports, 2021 Inertial particles advected by a background flow can show complex structures. We consider inertial particles in a 2D Taylor–Green (TG) flow and characterize particle dynamics as a function of the particle’s Stokes number using dynamic mode decomposition (
