Abstract

In this study we firstly conduct a simulation work to investigate the sound field and sensitivity field distribution characteristics of transmission type ultrasonic sensor in gas-liquid and oil-water two-phase flow by using the finite element analysis software COMSOL, and then we extract the average sensitivity (Savg) and sensitivity variation parameter (SVP) as the optimal index to optimize the structure of ultrasonic sensor and excitation frequency. The simulation results respectively indicate the correlativity between the sound pressure level attenuation and phase holdup in gas-liquid bubbly flow as well as oil in water two-phase flow.
