Journal ArticleDOI
Application of ultrasonic doppler method for bubbly flow measurement using two ultrasonic frequencies
TL;DR: In this paper, a new technique for multi-phase flow measurement is proposed, which is based upon an ultrasonic Doppler method (UDM) using different sizes of ultrasonic transducers (TDXs) for the UDM measurement.
Journal ArticleDOI
Application of ultrasonic multi-wave method for two-phase bubbly and slug flows
TL;DR: In this article, the authors proposed a measurement technique for two-phase bubbly and slug flows using ultrasound, which employs a unique ultrasonic transducer referred to as multi-wave transducers (TDX).
Journal ArticleDOI
A study of ultrasonic propagation for ultrasonic flow rate measurement
TL;DR: In this paper, an automatic three-dimensional (3D) sound field measurement system has been developed, and an experimental study has been conducted on ultrasonic properties by using this system, ultrasonic sound pressure distributions and radiation angles in water have been measured.
Journal ArticleDOI
Measurement of Bubbly Two-phase Flow in Vertical Pipe Using Multiwave Ultrasonic Pulsed Dopller Method and Wire Mesh Tomography
TL;DR: In this article, a multiwave ultrasonic pulsed Doppler (multiwave UVP) method and wire mesh tomography (WMT) have been applied to the measurement of bubbly two-phase flow.
