Multiphase velocity profile measurement using induced electromagnetic sensor array

本项目将进行一项可行性研究，使用交流和脉冲电磁场感应电压，以测量多相流中的连续相速度分布，其中连续相是导电体，分散相具有相对较低的电导率。可以设想，这种装置最终可以例如与双平面电阻层析成像（ERT）系统结合使用，以使得能够在两相（或三相）流中进行两个（所有）相的速度分布测量。最近在哈德斯菲尔德进行的数值模拟工作表明，感应电压电磁流量计可用于测量导电连续相的速度分布，并且混合物电导率的影响相对较小。一个18个月的研究助理将需要使用电极传感器阵列的电磁流量测量的理论和实验研究。该提案旨在实现一种新型电磁多相流量计的生成，该流量计具有对速度剖面测量的高性能动态响应的新能力，以及概念验证原型。

This project is to undertake a feasibility study using AC and pulsed electromagnetic fields to induce voltages for measuring the continuous phase velocity profile in multiphase flows where the continuous phase is an electrical conductor and the dispersed phase(s) has relatively low electrical conductivity. It is envisioned that such a device could ultimately be used, for example, in conjunction with a dual-plane Electrical Resistance Tomography (ERT) system to enable velocity profile measurements of both (all) phases to be made in two (or three) phase flows. Recent numerical simulation work at Huddersfield has demonstrated that induced voltage electromagnetic flow meters can be used for velocity profile measurement of the conducting continuous phase and that the influence of the mixture conductivity is relatively small. An 18-month research associate will be required for a theoretical and experimental study of electromagnetic flow measurement using an electrode sensor array. The proposal seeks to achieve the generation of a new type of electromagnetic multiphase flowmeter with the novel capability of a high performance dynamic response on velocity profile measurement, together with a proof-of-concept prototype.
