This article deals with the problem of separating solid particles in suspension by means of ultrasonics. The theoretical predictions of the action of acoustic radiation pressure on small dense particles are confirmed experimentally.


Die vorliegende Arbeit beschäftigt sich mit der Abscheidung fester, in Suspension befindlicher Teilchen mittels Ultraschall. Die theoretischen Vorhersagen bezüglich der Auswirkungen des Schallstrahlungsdruckes auf kleine Teilchen hoher Dichte wurden experimentell bestätigt.


Il s'agit du problème de séparer, au moyen des ultrasons, des particules solides en suspension dans un fluide. Nous confirmons expérimentalement les prédictions de la théorie en“ce qui concerne l'action de la pression de radiation acoustique sur des particules petites mais suffisamment denses.
