Non-invasive imaging of liquid/gas flow using ultrasonic transmission-mode tomography

Real-time process monitoring plays a dominant role in many areas of industry and scientific research concerning liquid/gas two-phase flow. It is proved that the operation efficiency of a process is closely related to accurate measurement and control of hydrodynamic parameters such as flow regime and...
