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…
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…
