Asymptotic closure model for inertial particle transport in turbulent boundary layers
Yan Zhang, Guiquan Wang, Andrew D Bragg
Transport equations for heavy inertial particles in turbulent boundary layers may be derived from an underlying phase-space probability density function (PDF) equation. These equat…
Off-center gravity induces large-scale flow patterns in spherical Rayleigh-Bénard
Guiquan Wang, Luca Santelli, Roberto Verzicco +2
Inspired by the hemispherical asymmetry observed in the Earth's inner core, we perform direct numerical simulations to study the effect of the gravity center offset in spherical Ra…
Diffusion-free scaling in rotating spherical Rayleigh-Bénard convection
Guiquan Wang, Luca Santelli, Detlef Lohse +2
Direct numerical simulations are employed to reveal three distinctly different flow regions in rotating spherical Rayleigh-Bénard convection. In the low-latitude region $\mathrm{I}…
When is settling important for particle concentrations in wall-bounded turbulent flows?
Andrew D. Bragg, David H. Richter, Guiquan Wang
We explore the role of gravitational settling on inertial particle concentrations in a wall-bounded turbulent flow. While it may be thought that settling can be ignored when the se…
Mechanisms governing the settling velocities and spatial distributions of inertial particles in wall-bounded turbulence
Andrew D Bragg, David H Richter, Guiquan Wang
We use theory and Direct Numerical Simulations (DNS) to explore the average vertical velocities and spatial distributions of inertial particles settling in a wall-bounded turbulent…
Transport and two-way coupling effect of inertial particles by large-scale and very-large-scale motions in turbulence
Guiquan Wang, David Richter
Direct numerical simulations two-way coupled with inertial particles are used to investigate the particle distribution and two-way coupling effect of low-inertia (…
Inertial particle velocity and distribution in vertical turbulent channel flow: a numerical and experimental comparison
Guiquan Wang, Kee Onn Fong, Filippo Coletti +1
This study is concerned with the statistics of vertical turbulent channel flow laden with inertial particles for two different volume concentrations ( and…
Two mechanisms of VLSM modulation by inertial particles in open channel flow
Guiquan Wang, David Richter
Very large-scale motions (VLSMs) and large-scale motions (LSMs) coexist at moderate Reynolds numbers in a very long open channel flow. Direct numerical simulations two-way coupled…
Modulation of the turbulence regeneration cycle by inertial particles in planar Couette flow
Guiquan Wang, David Richter
Two-way coupled direct numerical simulations are used to investigate the effects of inertial particles on self-sustained, turbulent coherent structures (i.e. the so-called the rege…
