Radial simulation research of gas-solid two phase annular flow with ultrasonic fluid measurement

Abstract

As for its application and universality, the research of gas-solid two-phase flow becomes popular, and annular flow is one of the common flow. By COMSOL software, radial simulation models are set up to study the different annular flow. It is simulated with different parameter annular flow and different frequency of ultrasonic, to research the sensitivity in diverse gas-solid flow. And also, the signals received by the ultrasonic sensor in different annular flow and frequency are analyzed. Thus, it offers theory analysis for diverse gas-solid two phase flow in the ultrasonic method.
