An apparatus for testing effects of relative movement of a fluid and an object has a test chamber (3) arranged to contain a fluid and is open in a manner to allow fluid inlet and/or outlet while the movable surface is moving. There is a drive (1) for moving a movable surface (13) with respect to the fluid in the chamber, and a probe for monitoring fluid conditions within the test chamber. The chamber has an inlet (5) and a separate outlet (6), and the drive is arranged to rotate a rotor (1) having the movable surface (13). |
