Accelerations of large inertial particles in turbulence
Yaning Fan, Cheng Wang, Linfeng Jiang +2
Understanding the dynamics of material objects advected by turbulent flows is a long standing question in fluid dynamics. In this perspective article we focus on the characterizati…
Numerical study on turbulence modulation of finite-size particles in plane-Couette flow
Cheng Wang, Linfeng Jiang, Chao Sun
Turbulent plane-Couette flow suspended with finite-size spheroidal particles is studied using fully particle-resolved direct numerical simulations. The effects of particle aspect r…
Sea Water Freezing Modes in a Natural Convection System
Yihong Du, Ziqi Wang, Linfeng Jiang +2
Sea ice is crucial in many natural processes and human activities. Understanding the dynamical couplings between the inception, growth and equilibrium of sea ice and the rich fluid…
Turbulence drag modulation by dispersed droplets in Taylor-Couette flow: the effects of the dispersed phase viscosity
Cheng Wang, Lei Yi, Linfeng Jiang +1
The dispersed phase in turbulence can vary from almost inviscid fluid to highly viscous fluid. By changing the viscosity of the dispersed droplet phase, we experimentally investiga…
Accumulation and alignment of elongated gyrotactic swimmers in turbulence
Zehua Liu, Linfeng Jiang, Chao Sun
We study the dynamics of gyrotactic swimmers in turbulence, whose orientation is governed by gravitational torque and local fluid velocity gradient. The gyrotaxis strength is measu…
Dynamics of finite-size spheroids in turbulent flow: the roles of flow structures and particle boundary layers
Linfeng Jiang, Cheng Wang, Shuang Liu +2
We study the translational and rotational dynamics of neutrally-buoyant finite-size spheroids in hydrodynamic turbulence by means of fully resolved numerical simulations. We examin…
How do the finite-size particles modify the drag in Taylor-Couette turbulent flow
Cheng Wang, Lei Yi, Linfeng Jiang +1
We experimentally investigate the drag modification by neutrally buoyant finite-size particles with various aspect ratios in a Taylor-Couette (TC) turbulent flow. The current Reyno…
Rotational dynamics of bottom-heavy rods in turbulence from experiments and numerical simulations
Linfeng Jiang, Cheng Wang, Shuang Liu +2
We successfully perform the three-dimensional tracking in a turbulent fluid flow of small asymmetrical particles that are neutrally-buoyant and bottom-heavy, i.e., they have a non-…
Ice front shaping by upward convective current
Ziqi Wang, Linfeng Jiang, Yihong Du +2
The extent and the morphology of ice forming in a differentially heated cavity filled with water is studied by means of experiments and numerical simulations. We show that the main…
Construction of fixed points of asymptotically nonexpansive mappings in uniformly convex hyperbolic spaces
Andrei Sipos
Kohlenbach and Leustean have shown in 2010 that any asymptotically nonexpansive self-mapping of a bounded nonempty -hyperbolic space has a fixed point. In this paper, we adapt…
From Rayleigh-Bénard convection to porous-media convection: how porosity affects heat transfer and flow structure
Shuang Liu, Linfeng Jiang, Kai Leong Chong +6
We perform a numerical study of the heat transfer and flow structure of Rayleigh-Bénard (RB) convection in (in most cases regular) porous media, which are comprised of circular, so…
Rotation of anisotropic particles in Rayleigh-Bénard turbulence
Linfeng Jiang, Enrico Calzavarini, Chao Sun
Inertialess anisotropic particles in a Rayleigh-Bénard turbulent flow show maximal tumbling rates for weakly oblate shapes, in contrast with the universal behaviour observed in dev…
Robustness of heat-transfer in confined inclined convection at high-Prandtl-number
Linfeng Jiang, Chao Sun, Enrico Calzavarini
We investigate the dependency of the magnitude of heat transfer in a convection cell as a function of its inclination by means of experiments and simulations. The study is performe…
