Large-eddy simulation and modeling of Taylor-Couette flow with an outer stationary cylinder
Wan Cheng, Dale I. Pullin, Ravi Samtaney
We present wall-resolved large-eddy simulations (LES) of the incompressible Navier-Stokes equations together with empirical modeling for {turbulent} Taylor-Couette {(TC)} flow wher…
