MODELIZATION OF THE ACCUMULATION OF PARTICLES UNDER THE ULTRASOUND INFLUENCE ON A CENTRIFUGAL DUST FILTER SYSTEM

Abstract

A mathematical model of the accumulation of diffuse particles in the air
environment under the effect of the ultrasound is proposed. The model is
established based on a set of equations of Smoluchowski which describes the
kinematic of accumulation process and take into account viscosity of the dust-air
stream. This model is to calculate the impact probability elements between a
particle couple (with a determined dimension of particles) in the dust-air stream.
Results demonstrate the influence of the particle concentration in the dust-air
stream on the efficiency of a centrifugal dust filter system with and without the
participation of the ultrasound.
