Doppler droplet/bubble mean diameter sizing method

Bubbles and drops oscillate in two-phase flows. Frequency is known function of diameter. The Doppler signal processing provides information about velocity and size of a dispersed phase. The sizes of the attached to a solid surface bubbles are measured by independent methods. The measurement accuracy of object diameter is within 10%.
