Conductance Sensors for Multiphase Flow Measurement: A Review
TL;DR: In this paper, a review on the basic sensing principle, different types of conductance sensors and their applications in flow monitoring, flow pattern identification, phase fraction determination and velocity measurement of multiphase flow is presented.
Journal ArticleDOI
Numerical investigations of the accuracy of conductivity wire-mesh sensors
TL;DR: In this article, a cuboid with zero conductivity was introduced in 9'×'9 WMS potential field simulations, and the results indicated that the systematic error caused by the uniform sensitive volume assumption increases in the wire plane axial distance.
Journal ArticleDOI
Statistical Characterization of Flow Structure of Air–water Two-phase Flow in Airlift Pump–Bubble Generator System
TL;DR: In this article, the authors identify the flow structure in an air-lifted pump-bubble generator system by using experimentally obtained differential pressure signals, and the results indicate that the water movement mechanism in the riser pipe could be divided into three regions, namely fixed liquid, locally moving liquid and fully moving liquid, depending on the supplied superficial air velocity.

Detached eddy simulations of rising Taylor bubbles
H. Shaban,Stavros Tavoularis +1 more
TL;DR: In this paper, a numerical study of turbulent flow induced by Taylor bubbles rising in a stagnant liquid column is presented, where predictions of the void fraction, mean velocity and turbulent fluctuations are compared with available experimental results.
Journal ArticleDOI
Effective elastic constants of wire mesh material studied by theoretical and finite element methods
TL;DR: In this paper, a theoretical model was proposed to calculate the anisotropic effective elastic constants of a wire mesh material, and finite element method (FEM) was also carried out to validate the proposed model.

Convective boiling and condensation
John G. Collier,John R. Thome +1 more
TL;DR: In this paper, the basic models of two-phase flow are discussed and empirical treatments of two phase flow are provided. But the authors focus on convective boiling and condensing.

Theory of Multicomponent Fluids
TL;DR: In this article, the authors propose an approach for modeling multicomponent flows based on the classical theory of solutions of solutions, which they call well-posedness and well-posedness.

A new electrode-mesh tomograph for gas–liquid flows
TL;DR: In this article, an electrode-mesh tomograph for high-speed visualisation of transient gas fraction distributions in two-phase flows in pipes is presented, which is based on the measurement of the local instantaneous conductivity of the 2-phase mixture.
Journal ArticleDOI
Capacitance wire-mesh sensor for fast measurement of phase fraction distributions
TL;DR: In this paper, a wire-mesh sensor based on capacitance measurements is proposed to measure transient phase fraction distributions in a flow cross-section, such as in a pipe or other vessel, and is able to discriminate fluids having different relative permittivity values in a multiphase flow.
Journal ArticleDOI
Bubble size measurement using wire-mesh sensors
TL;DR: In this article, a wire-mesh sensor with a time resolution of 12 kHz was used to measure bubble size distributions in a gas-liquid flow, which is designed for a pipe of 512 mm diameter and consists of two electrode grids with 16 electrodes each, put in the flow direction behind each other.
