摘要：

Aerosol droplet genesis by ultrasonic atomization has been theoretically studied using a model for three-dimensional spherical/ellipsoidal waves generated by excitation of a system of given geometry by forced frequency of an ultrasonic oscillator. Analyzing the harmonic function of the rate potential, an equation has been derived that defines the mean diameter and the distribution spectrum of aerosol droplets formed at the surface of a liquid. Comparison has been made between the calculated values for the mean particle sizes and their distribution with those obtained experimentally for Al2O3, mullite and cordierite powders synthesized from different precursors.
