As described above, the conventional flow environment simulation circulating water tank that reproduces the flow (front-back flow) near the sea floor caused by waves in the actual open sea on the upper open surface of the circulating water tank has a piston. Since the flow is generated by using, the stroke of the piston becomes long and the piston becomes large.

Further, the stroke of the piston and the cross-sectional area of the piston are in inverse proportion to each other. For example, if the stroke of the piston is to be halved, the cross-sectional area of the piston may be doubled, but Since the area becomes large, the piston also becomes large in this case.

As described above, in the conventional flow environment simulation circulating water tank, either the stroke of the piston is long or the cross-sectional area of the piston is large. In either case, the piston becomes large. Due to this, there is a disadvantage that the circulating water tank also becomes large.
