Abstract

A new method has been developed to measure in situ size distribution of drops in gas-liquid dispersoids in multiphase flow. The principle of the method is simple: a drop of electrically conductive liquid contacting two needle point electrodes in a DC circuit produces a pulse of current which can be totalized in an electronic counter. By varying the needle point spacing an average count rate curve is obtained from which the drop size distribution can be calculated. Analysis of neither pulse size nor duraction is required. Typical results for an air-water system in dispersed flow are presented.
