Résumé

Turbulent Taylor-Couette flows between two cylinders with the inner cylinder rotating are simulated using Direct Numerical Simulation (DNS) at a radius ratio of 0.67 and at two Reynolds numbers to investigate the Reynolds number effects on the flow. It is found that the results are consistent with the experimental results at the same radius ratio. Particular attention is given to the turbulent structures of the flows.
