The state of the art of study of turbulent flow structure in an axially rotating cylindrical channel is presented. The computation results for components of mean velocity vector, Reynolds-stress and third-moment tensors have been obtained for a flow in stationary and rotating pipes. Several simple algebraic models for triple correlations are used in the second-moment closure and tested by comparison with available measured data for two different cases of pipe rotation. The first case corresponds to the pipe section with characteristics changing along the pipe axis, whereas the second case is a developed rotating pipe flow. The influence of rotation terms in the third-moment approximations on first-, second- and third-order moments is studied. The behavior of turbulent intensities along the pipe axis is discussed.
