Experimental investigation into Lagrangian statistics of droplets in homogeneous isotropic turbulence
Lu Li, Yi-Bao Zhang, Yaning Fan +2
We experimentally investigate the Lagrangian dynamics of finite-sized, neutrally buoyant droplets in homogeneous isotropic turbulence. The droplet size follows a log-normal distrib…
Active biphasic heat transfer enhancement in vertical natural convection
Haoran Qi, Chaoben Zhao, Yaning Fan +3
Vertical natural convection (VC), often cannot meet the high heat transfer demands due to the inherent misalignment of the direction of buoyancy (vertical) with the direction of th…
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…
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…
