Global drag reduction and local flow statistics in Taylor-Couette turbulence with dilute polymer additives
Yi-Bao Zhang, Yaning Fan, Jinghong Su +2
We present an experimental study on the drag reduction by polymers in Taylor-Couette turbulence at Reynolds numbers () ranging from to . In this…

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…
