Turbulence decay towards the linearly-stable regime of Taylor-Couette flow
Rodolfo Ostilla Mónico, Roberto Verzicco, Siegfried Grossmann +1
Taylor-Couette (TC) flow is used to probe the hydrodynamical stability of astrophysical accretion disks. Experimental data on the subcritical stability of TC are in conflict about…
Velocity profiles in strongly turbulent Taylor-Couette flow
Siegfried Grossmann, Detlef Lohse, Chao Sun
We derive the velocity profiles in strongly turbulent Taylor-Couette flow for the general case of independently rotating cylinders. The theory is based on the Navier-Stokes equatio…
Boundary layer dynamics at the transition between the classical and the ultimate regime of Taylor-Couette flow
Rodolfo Ostilla Monico, Erwin P. van der Poel, Roberto Verzicco +2
Direct numerical simulations of turbulent Taylor-Couette flow are performed up to inner cylinder Reynolds numbers of {Re_i=10^5} for a radius ratio of {η=r_i/r_o=0.714} between the…
Optimal Taylor-Couette flow: Radius ratio dependence
Rodolfo Ostilla Monico, Sander G. Huisman, Tim J. G. Jannink +5
Taylor-Couette flow with independently rotating inner (i) and outer (o) cylinders is explored numerically and experimentally to determine the effects of the radius ratio η on the s…
The unifying theory of scaling in thermal convection: The updated prefactors
Richard J. A. M. Stevens, Erwin P. van der Poel, Siegfried Grossmann +1
The unifying theory of scaling in thermal convection (Grossmann & Lohse (2000)) (henceforth the GL theory) suggests that there are no pure power laws for the Nusselt and Reynolds n…
