METHOD AND APPARATUS FOR INVESTIGATING MULTIPHASE FLOW PROPERTIES USING A SWIRL INDUCER FOLLOWED BY A FLOW CONSTRICTION

摘要

A method is provided for investigating a gas-liquid fluid mixture as it is conveyed in a conduit having a first constriction region providing a reduced conduit cross section. The method includes the steps of inducing the mixture to exhibit swirling flow in the first constriction region, thereby separating the liquid from the gas; and determining one or more properties of the fluid in the first constriction region.
