THE DISPERSED BUBBLES TWO-PHASE FLOW MODEL : THEORY AND APPLICATION
ABSTRACT
This paper is concerned with the equations of motion for the dispersed bubbly flows. The equations are analysed by taking into account the aspects of the relative motion of the bubbles. It is found that the characteristics are real. By analyzing the sound velocity in liquids containing bubbles it appears that two applications can be considered. One concerns critical flow through a convergent-divergent Laval nozzle, where the results establish a relation between the phase velocities, the void fraction and the sound velocity in the mixture. This relation agrees very well with experimental data and with other authors models. Another application concerns the cavitation phenomena in which the classical analysis of transient homogeneous-flow models are fully verified.
