N2 - We performed a series of direct numerical simulation (DNS) of the rotating turbulent channel flow in low Reynolds-number and rotation-number ranges, in order to investigate presence or absence of turbulent stripe, i.e., large-scale laminarturbulent banded pattern, in the rotating Poiseuille flow and to elucidate the transitional process in terms of structures including longitudinal roll cells induced by the Coriolis force. As a result, we found that the turbulent stripe occured only in flows with weak (or no) spanwise system rotations and coexisted with the roll cell under a limited condition. We investigated relationships between the dominant-structure alterations and the changes of rotation-number dependencies of statistics.
