Abstract

A new method of measuring bubble size and velocity simultaneously in three-phase suspension flows by using a reference beam LDA system is developed in response to the need of the new, novel method of extracting additional underground oil by the introduction of compressed gas. Three photodetectors are used to obtain velocity, blocking period and other information of bubble characteristics. The operational principle, calculations, the block diagrams of discrimination and control logic circuits are described. Experimental investigations and sample results on bubble size and velocity measurements are also presented.
