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…
