Experimental study of velocity statistics in wall-bounded turbulent emulsions

Yaning Fan, Yi-Bao Zhang, Jinghong Su +3

Turbulent emulsions are ubiquitous in chemical engineering, food processing, pharmaceuticals, and other fields. However, our experimental understanding of this area remains limited…

Lagrangian flow statistics in experimental homogeneous isotropic turbulence

Cheng Wang, Sander G. Huisman, Thomas Basset +2

We report on Lagrangian flow statistics from experimental measurements of homogeneous isotropic turbulence. The investigated flow is driven by 12 impellers inside an icosahedral vo…

How interfacial tension enhances drag in turbulent Taylor-Couette flow with neutrally buoyant and equally viscous droplets

Jinghong Su, Yi-bao Zhang, Cheng Wang +5

The presence of dispersed-phase droplets can result in a notable increase in the system's drag. However, our understanding of the mechanism underlying this phenomenon remains limit…

Turbulence modulation in liquid-liquid two-phase Taylor-Couette turbulence

Jinghong Su, Cheng Wang, Yi-bao Zhang +3

We investigate the coupling effects of the two-phase interface, viscosity ratio, and density ratio of the dispersed phase to the continuous phase on the flow statistics in two-phas…

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 the mechanism of drag modulation by dispersed drops in two-phase Taylor-Couette turbulence

Jinghong Su, Lei Yi, Bidan Zhao +4

The presence of a dispersed phase can significantly modulate the drag in turbulent systems. We derived a conserved quantity that characterizes the radial transport of azimuthal mom…

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…

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…

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-…

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…
