Abstract

An analogy is drawn between the onset of minimum spouting and the bubbling-to-spray transition on a sieve tray to derive an analytical equation which relates the bed depth to the minimum air velocity required for the onset of spouting. The derived equation and the significance of the terms appearing in it are discussed and compared with existing correlations and the available data.

Abstract

On fait une analogie entre le commencement du “spouting” minimal et la transition barbotage-giclage sur un plateau perforé; le but recherché est de développer une équation analytique qui relie la profondeur du lit et la vitesse minimale de l'air nécessaire pour le commencement du “spouting”. On discute l'équation ainsi établie et l'importance des termes qu'elle contient et on les compare avec les corrélations et les données existantes.
