Propagation characteristics of ultrasonic signals in gas-liquid two-phase flow
Research on the propagation and attenuation characteristics of ultrasonic waves in gas-liquid two-phase flow. According to the related theory of ultrasound, using COMSOL multiphysics simulation software, through the geometric modeling, meshing and full The definition of local parameters is used to study the propagation and attenuation characteristics of ultrasonic signals in different media compared with gas. The propagation process of ultrasonic signals in two-phase flow at different times and the attenuation characteristics of ultrasonic signals in different gas phases are simulated. The results show that with the increase of the gas phase, the attenuation amplitude of the ultrasonic signal increases continuously.
