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.

L'invention concerne un appareil de test aérodynamique ou hydrodynamique qui permet que tout l'air soit évacué de l'enceinte de test, de façon qu'il ne reste aucune surface dépourvue de liquide. Ceci permet un test plus précis de structures, plus particulièrement à de faibles nombres de Reynolds. Cet appareil comprend un joint qui permet d'éliminer une surface dépourvue de liquide. Le joint est placé dans une fente sur une surface supérieure de l'enceinte et peut comprendre au moins un élément de joint gonflable. La surface supérieure de l'enceinte est de préférence inclinée en direction du joint pour empêcher l'emprisonnement de bulles d'air dans l'enceinte. L'invention concerne également un procédé de test mettant en oeuvre un tel appareil.
