ACOUSTIC DETERMINATION OF BUBBLE SIZE DISTRIBUTION
Abstract
The purpose of the investigation was to determine the feasibility of measuring bubble size distributions acoustically. The experiment consisted of a comparison of a photographically and an acoustically determined bubble size distribution of an electrolytically generated bubble screen. The approximate range of bubble radii considered was from 15 to 85 microns. Results indicate the acoustic method may be reasonably accurate in determining a relative bubble size distribution for spherical bubbles with radii greater than 32 microns, but more information is needed about the damping constants of nonresonant bubbles; and a more precise evaluation of an integral in the acoustical theory is needed before the validity of the acoustical method can be established.
