Abstract
It is experimentally demonstrated for the first time that the precipitation of a multitude of unconsolidated particles can be accompanied by the formation of a heterogeneously dispersive layer in which standing waves arise under the effect of propagating ultrasonic waves. The time required for such a layer to form from the multitude of particles is directly related to the individual properties of both the disperse phase and the dispersive medium. The experiments are performed at an ultrasonic frequency of 3 MHz. The disperse phase is represented by starch and Al2O3 particles, and the dispersive media are water and a glycerin solution.
