A peculiar wavy flow occurring in a rotating channel through which fluids flow radially is studied experimentally and theoretically. This wavy flow is created by a Coriolis force which arises from uneven distributions of flow velocities due to the inlet bend of the channel. The wavy nature of the flow is analyzed by using the momentum theory, and the result is verified by experiments. The following results are obtained : (1) The pitch of the wavy flow is reversely proportional to Ω, the reciprocal of which is a Rossby number. (2) The wavy motion damps downstream due to the wall friction. (3) The pitch of the wavy flow is almost independent of the inlet curvature.
