Flow measurement with an electromagnetic flowmeter in two-phase bubbly and slug flow regimes
TL;DR: In this article, an alternating-current electromagnetic flowmeter was designed and manufactured to investigate the characteristics of an electromagnetic flow meter in two-phase flow, in which a rod-shaped nonconducting material was used, and the effect of bubble position and void fraction on the flow meter was investigated.

Measurement of void fraction and bubble speed of slug flow with three-ring conductance probes
TL;DR: In this article, the void fraction, shape, and velocity of a single slug bubble in a vertical 25.4mm-diameter circular tube equipped with two three-ring conductance probes were measured.

Advanced electromagnetic flowmetry for slug flow: numerical signal prediction and calibration
TL;DR: In this article, the velocity fields of axisymmetric gas-liquid slug flow in a vertical pipe were obtained using volume-of-fluid (VOF) method and the virtual potential distributions for the electrodes of finite size were also computed using the finite volume method for the simulated slug flow.

A current-sensing electromagnetic flowmeter for two-phase flow and numerical simulation of the three-dimensional virtual potential distribution: I. Fundamentals and annular flow
TL;DR: In this paper, the authors proposed a flow pattern coefficient to separate the dependence on the flow configuration of the two-phase flow from that on the liquid conductivity, which can be expressed with the calibration of single phase flow.

An experimental study on the characteristics of electromagnetic flowmeters in the liquid metal two-phase flow
TL;DR: In this paper, the characteristics of AC electromagnetic flowmeter were investigated in the liquid metal two-phase flow, encompassing bubbly to slug flow regimes, were conducted with the liquid sodium-nitrogen mixture.
