Turbulence Modeling of Torsional Couette Flows

Table 1

Influence of the mesh grid on the mean and turbulent fields for 𝐺=0.02, Re=10⁶, and 𝐶_𝑤=0. Comparisons with the 200×80 mesh which is chosen as the reference mesh grid.

Difference with the 200×80 mesh	250×80	300×80	250×100
Mean field	0.5%	0.6%	0.5%
Turbulent field	1.9%	2.1%	2%
