The relationship between the growth of inlet reverse flow and the change in separation point in a suction flow was studied experimentally in a helical inducer. The relationship between the decrease in flow rate and the change in pressure distribution on a suction pipe wall was examined in detail at the point where the inlet reverse flow occurs. Furthermore, flow visualization, with the aid of the streakline method, was carried out to observe the occurrence of flow separation in the suction pipe flow. As a result of the present study, it is confirmed that the separation in a suction pipe occurs just upstream of the inlet reverse flow region. It is also known that the adverse pressure gradient appears in the pipe flow in the partial capacity range, which may be considered as a cause of the suction flow separation.
