Statistics of velocity gradient and vortex sheet structures in polymeric turbulent von K{á}rm{á}n swirling flow
Feng Wang, Yi-Bao Zhang, Ping-Fan Yang +1
Investigations into the effects of polymers on small-scale statistics and flow patterns were conducted in a turbulent von Karman swirling (VKS) flow. We employed the tomographic pa…
Temporal modulation on mixed convection in turbulent channels
Ao Xu, Rui-Qi Li, Heng-Dong Xi
We studied flow organization and heat transfer properties in mixed turbulent convection within Poiseuille-Rayleigh-Bénard channels subjected to temporally modulated sinusoidal wal…
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…
Particle transport and deposition in wall-sheared thermal turbulence
Ao Xu, Ben-Rui Xu, Heng-Dong Xi
We studied the transport and deposition behaviour of point particles in Rayleigh-Bénard convection cells subjected to Couette-type wall shear. Direct numerical simulations (DNSs)…
