Instantaneous velocity of multiphase flow is an important parameter in scientific and
industrial applications such as fluid mechanics modeling and flow measurement and …

Acoustic methods applied to opaque systems have attracted the attention of researchers in
fluid mechanics. In particular, owing to their ability to characterise in real-time, non …

Water-based dispersed wavy flow, whereby the water with dispersed oil droplets moves
along the bottom of the pipe and the gas concurrently on the top, is a frequently encountered …

Ultrasound reflects strongly off the gas–liquid interface when there is a large change in
acoustic impedance. We exploit this phenomenon to detect the instantaneous position of the …

The motion of single Argon bubbles rising in the eutectic alloy GaInSn under the influence of
a DC longitudinal magnetic field (parallel to the direction of bubble motion) was examined …

Oil-water two-phase flow commonly exists in many industries. The accurate measurement of
flow velocity is beneficial for safety operation and economic efficiency. A combination of a …

Phase fraction of oil–water two-phase flow is important to the process control and
optimization. In this paper, a prediction model based on the mechanism of ultrasound …

In industrial environments, having instrumentation able to attain fast, accurate, and
autonomous measurements is pivotal to understanding the dynamics of liquid and particles …

A flow velocity measurement method based on continuous wave ultrasound Doppler
(CWUD) and flow profile modeling is presented. A theoretical model is proposed to relate …

This paper proposes a measurement technique for two-phase bubbly and slug flows using
ultrasound. In order to obtain both liquid and gas velocity distributions simultaneously, a new …
