Inner flow of two kinds of circular cylinders is investigated by using hydrogen bubble method. Each cylinder of one group has one suction slit and two discharge slits. Each of the other group has one suction slit and one discharge slit. Each cylinder of the latter group has a rear plate near the discharge slit.
Results of flow visualization show that the velocity of the inner flow of the tested cylinders changes variously according to the inlet flow direction. In the case of the former group, when the outer flow is directed toward discharge slit, reverse flow is observed in the cylinder. On the other hand, inner reverse flow is not observed in the latter group of the cylinder.
