Determination of bubble size distribution in gas–liquid two‐phase systems via an ultrasound‐based method

摘要

Over the past few years, ultrasonic techniques are increasingly used to determine bubble size distribution in gas–liquid two‐phase systems. However, the development of a precise and efficient measuring system is very challenging because bubbles are dynamic and unstable relative to time and space in a moving fluid, thus hindering an accurate validation of the measuring system. Therefore, this study examined the possibility of using artificial bubbles to establish an ultrasonic measuring system.
