Inertial migration of a non-neutrally buoyant particle in a linear shear flow with thermal convection

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (6)

We perform numerical simulations on inertial migration of a non-neutrally buoyant particle with a density ratio of 0.98-1.02 in a linear shear flow do......

Unexpected scaling of interstitial velocities with permeability due to polymer retention in porous media

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (8)

Polymer retention from the flow of a polymer solution through porous media results in substantial decrease of the permeability; however, the underlyin......

Lagrangian velocity and acceleration measurements in plume-rich regions of turbulent Rayleigh-Benard convection

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (5)

We report an experimental study of Lagrangian velocity and acceleration in turbulent Rayleigh-Benard convection using particle tracking velocimetry, w......

Composite active drag control in turbulent channel flows

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (5)

A composite drag control (CDC) combining the opposition (OC) and spanwise opposed wall-jet forcing (SOJF) methods is studied in a turbulent channel fl......

Numerical investigation of ventilated cavitating flow in the wake of a circular cylinder

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (6)

Ventilated cavitating flow of a circular cylinder is investigated by numerical simulation. The coupled level set and volume of fluid method is used to......

Rayleigh-Benard convection in a dielectric fluid under an external electric field with a melting boundary

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (6)

We perform a numerical analysis of Rayleigh-Benard convection during solid-liquid phase change in the presence of an electric field. The objective is ......

Diffraction of weakly unstable detonation through an obstacle with different sizes and shapes

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (4)

Detonation diffraction has been extensively studied because it is a very fundamental problem and has broad practical applications. In this study, two-......

Third-order structure function in the logarithmic layer of boundary-layer turbulence

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (7)

Townsend's attached eddy hypothesis (AEH) gives an accurate phenomenological description of the flow kinematics in the logarithmic layer, but it suffe......

Effect of aspect ratio on flow through and around a porous disk

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (7)

We numerically investigated steady axisymmetric flow through and around a porous disk with aspect ratio (chi) ranging from 1 to 20, Reynolds number (R......

Stability of a thin viscoelastic film falling down an inclined plane

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (8)

The stability of a thin viscoelastic film of Oldroyd-B fluid falling down an incline is investigated. In the weak viscoelasticity limit, a reduced mod......

Stochastic dynamical model for space-time energy spectra in turbulent shear flows

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (5)

Space-time energy spectra describe the distribution of energy density over space and timescales, which are fundamental to studying dynamic coupling at......

Simulating particle settling in inclined narrow channels with the unresolved CFD-DEM method

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (3)

Acceleration of particle settling in inclined containers, known as the Boycott effect, is a common natural phenomenon, which can significantly affect ......

Constrained large-eddy simulation of turbulent flow over rough walls

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (4)

Recent research indicates that the structure of the wall-bounded turbulence depends on the mean shear created by the wall. To examine the response of ......

Kinetic energy transfer in compressible homogeneous anisotropic turbulence

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (6)

Kinetic energy transfer in compressible homogeneous anisotropic turbulence is studied by numerical simulations of forced anisotropic turbulence (FAT) ......

Reducing droplet contact time and area by craterlike surface structure

期刊: PHYSICAL REVIEW FLUIDS, 2021; 6 (8)

Reduction in contact time and area between the rebounding droplet and the solid surface has attracted great attention due to the potential application......
