ABSTRACT:
An aerodynamic or hydrodynamic test apparatus that permits all air to be evacuated from the test enclosure, such that no free liquid surfaces remain. This permits more accurate testing of structures, particularly at low Reynolds numbers. The apparatus includes a seal that allows the elimination of a liquid free surface. The seal is disposed in a slit on an upper surface of the enclosure and can include one or more inflatable sealing members. The upper surface of the enclosure is preferably sloped upwardly towards the seal to prevent the entrapment of air bubbles within the enclosure. A method of testing using such an apparatus is also disclosed.
