Abstract

Un rideau d'air (1) est créé dans un espace d'air libre (2) en partie par un premier courant d'air passant par un ou plusieurs ajutages (4) et en partie par un second courant d'air (5) formant une couche superficielle (5a) autour du rideau d'air, des moyens (6) étant prévus pour permettre de créer une circulation d'air dans un sens allant à l'encontre de celui de la circulation que le frottement de la couche superficielle (5a) tend à donner à l'air adjacent de l'espace d'air (2).
