Direct numerical simulation of Taylor-Couette flow with grooved walls: torque scaling and flow structure

Xiaojue Zhu, Rodolfo Ostilla Mónico, Roberto Verzicco +1

We present direct numerical simulations of Taylor-Couette flow with grooved walls at a fixed radius ratio $\eta =r_i/r_o=0.714$ with inner cylinder Reynolds number up to $Re_i=3.76\tim…
