Effects of rough walls on sheared annular centrifugal Rayleigh-Bénard convection
Fan Xu, Jun Zhong, Jinghong Su +4
In this study, we investigate the coupling effects of roughness and wall shear in an annular centrifugal Rayleigh-Bénard convection (ACRBC) system, where two cylinders rotate with…
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…
Direct numerical simulation of Taylor-Couette flow with vertical asymmetric rough walls
Fan Xu, Jinghong Su, Bin Lan +4
Direct numerical simulations are performed to explore the effects of rotating direction of the vertical asymmetric rough wall on the transport properties of Taylor-Couette (TC) flo…
