Abstract
A low-Reynolds-number second moment closure is improved with the aid of DNS data and applied to turbulent channel flows with a spanwise rotation. Shima's pressure strain model is refined and a multiple source model is introduced for the exact ε equation. Computational results for the turbulent plane channel flows rotating in orthogonal mode are compared with the DNS, LES and experimental data. The present second moment closure achieves a level of agreement with DNS data similar to those for the non-rotating flow cases. In particular, it yields the improved performance in predicting the distributions of ε in the near wall sublayer.
