摘要

The present analysis shows that the EVM can not reflect the tur-bulence physics in non-inertial frame. The effects of Coriolis force on turbulence isembodied naturally in the Reynolds-stress transport equation. It is observed thatthe existing second-moment closure model with appropriate near-wall treatment canadequately predict flows in rotating channel and in axially rotating pipe for moderaterotation rate.
