Investigating the Characteristics of Two-Phase Flow Using Electrical Capacitance Tomography (ECT) for Three Pipe Orientations

Electrical capacitance tomography two-phase oil-gas pipe flow imaging by the linear back-projection algorithm

Electrical Capacitance Tomography (ECT) is a novel technology that can deal with the complexity of two-phase gas-oil flow measurement by explicitly deriving the component distributions on two adjacent planes along a pipeline. One of its most promising applications is the visualization of gas-oil flows. ECT offers some advantages over other tomography modalities, such as no radiation, rapid resp...

Visualisation of Two-phase Gas-liquid Pipe Flows Using Electrical Capacitance Tomography

Electrical Capacitance Tomography (ECT) can be used to measure concentration and velocity distributions in two-phase flows. ECT is non-intrusive, and the reconstruction of the concentration and velocity distribution can be undertaken in real time and over an arbitrary number of zones in the flow cross-section. The concept of a ‘virtual instrument’ is introduced where zones of the image can be s...

Mass Flow Measurement of Biofuels using Electrical Capacitance Tomography

Biomass provides 10% of the global energy supply and electricity generation from biomass and waste is expected to increase by a factor of 4 by 2030. Currently efficiency of biomass power generation is poor and IEA targets improvements from 18% to 25% by 2030 [1]. Such increases in efficiency will require significant new technology and accurate real-time measurement of the flow of these highly v...

Stability analysis for two - phase pipe flow

Analysis of the nonlinear axial vibrations of a cantilevered pipe conveying pulsating two-phase flow

The parametric resonance of the axial vibrations of a cantilever pipe conveying harmonically perturbed two-phase flow is investigated using the method of multiple scale perturbation. The nonlinear coupled and uncoupled planar dynamics of the pipe are examined for a scenario when the axial vibration is parametrically excited by the pulsating frequencies of the two phases conveyed by the pipe.
