The principal aim of the research proposal is to develop a next generation multi-phase flow instrument to non-invasively measure the phase flow rates, and rapidly image the flow-field distributions, of complex, unsteady two- or three-phase flows. The proposed research is multi-disciplinary covering aspects of fluid mechanics modelling, sensor material selection and flow metering, process tomography and multi-variable data fusion. The new instrument will be based on the novel concepts of 3D vector Electrical Impedance Tomography (EIT) and the Electromagnetic Velocity Profiler (EVP). These will be used in conjunction with auxiliary differential-pressure measurements for flow density and total flow rate. It is our intention to be able to measure the volumetric flow rate, image time-dependent distributions of the local axial velocity and volume fraction of the dispersed and continuous phases, visualise flow patterns and provide an alternative measurement of volumetric flow rates in two and three phase flows. The project draws upon several recent advances in EIT technology made by the proposers' research teams. Together these potentially enable the development of an advanced flow meter intended to address some limitations of current multiphase flow meters, leading to improvements of the management of productivity in many industrial sectors such as petroleum, petrochemical, food, nuclear and mineral processing. Within the scope of this research, only flows with a conductive continuous liquid phase will be targeted. We will make use of advanced Magnetic Resonance Imaging (MRI) protocols for independent non-invasive validation of both the phase volume fraction and velocity distribution measurements. It is intended that the project will pave the way for the manufacturing of a next generation of advanced multi-phase flow measurement and rapid visualisation technologies.

该研究方案的主要目的是开发新一代多相流仪器，以非侵入性地测量复杂的、非定常的两相或三相流动的相流量，并快速成像流场分布。该研究涉及多学科领域，包括流体力学建模、传感器材料选择和流量测量、过程层析成像和多变量数据融合。新仪器将基于三维矢量电阻抗断层成像(EIT)和电磁速度剖面仪(EVP)的新概念。它们将与流量密度和总流量的辅助差压测量一起使用。我们的目标是能够测量体积流量，成像分散相和连续相的局部轴向速度和体积分数随时间的分布，可视化流型，并提供两相和三相流动中体积流量的替代测量。该项目借鉴了提出者研究团队在EIT技术方面取得的几项最新进展。这些都可能使先进流量计的开发成为可能，旨在解决当前多相流量计的一些局限性，从而改善石油、石化、食品、核和矿物加工等许多工业部门的生产率管理。在本研究的范围内，只有具有导电性的连续液相流动才是目标。我们将利用先进的磁共振成像(MRI)协议对相体积分数和速度分布测量进行独立的非侵入性验证。该项目旨在为制造下一代先进的多相流测量和快速可视化技术铺平道路。
