In order to realize the core flow without using wheels, we experimentally investigate effects of helical ribs caved in a side surface of the capsule. The capsule has 4 ribs of 3mm height or 5mm height. The angle of rib coiling the capsule outer diameter is varied five kinds. The diametrical clearance between the pipe and capsule is 4mm for capsule used. When the capsule mass is small, the capsule velocity is faster then the average water velocity. When an inlet pressure head becomes lower, the capsule of 5mm rib height moves lower than the water flow, although the capsule of 3mm rib height still moves faster than that. When the capsule mass becomes large, the capsule velocity becomes lower than the water flow as well. But the capsule velocity is increased when the angel of rib becomes large. Finally, we observed that the pattern of pressure difference at the popeline is influenced by the capsule surface geometry and the capsule mass.
