Flow dynamics of Solid-Liquid Suspensions in Processing Equipment

我们有一个大型的多学科EPSRC研究计划（2017-2021），该计划已经开始研究各种流动系统（例如微通道，管道，搅拌容器）中的多尺度两相固液流动。这项工作包括与萨里大学和达斯伯里实验室的合作，并且有可能进行工业合作。我们希望将博士项目与EPSRC项目联系起来，这样，学生将受益于与经验丰富的博士后研究人员一起工作和互动。也有可能进行产业合作。固液悬浮液在各种尺度的管道和容器中的运动是一个普遍的复杂问题。依赖固液流动的行业有很多，包括化工、消费品、食品、制药、石油、采矿、河流工程、建筑、发电、生物技术和生物医学。该项目将使用先进的拉格朗日（正电子发射粒子跟踪（PEPT））和欧拉粒子成像测速（PIV）和微PIV)流动成像技术解决一些实验挑战，以发展对不同尺度（微观，中观，宏观）流动系统中固液流动相关现象的缺失物理理解。该工作还将酌情与其他合作伙伴合作解决项目的理论问题，根据候选人的背景和兴趣，可能包括数值模拟（例如CFD）。

We have a large multi-disciplinary EPSRC research programme (2017-2021) which has started looking at multiscale two-phase solid-liquid flows in various flow systems (e.g. microchannels, pipes, stirred vessels). The work includes collaboration with the University of Surrey and Daresbury Laboratory, and there is possibility for industrial collaboration. We would like to link a PhD project to this EPSRC programme, thus, the student will benefit from working alongside and interacting with experienced postdoctoral research fellows. There is also possibility for industrial collaboration.The movement of solid-liquid suspensions in pipes and vessels of various scales is a generic complex problem. Industries dependent on solid-liquid flow are numerous including chemicals, consumer goods, food, pharmaceuticals, oil, mining, river engineering, construction, power generation, biotechnology and biomedical. This project will address some of the experimental challenges of the problem using advanced Lagrangian (positron emission particle tracking (PEPT) and Eulerian particle imaging velocimetry (PIV) and micro-PIV) flow imaging techniques to develop the missing physical understanding of the pertinent phenomena of solid-liquid flow in different flow systems across the scales (micro, meso, macro). The work will also address, as appropriate, theoretical aspects of the project in collaboration with the other partners, which may include numerical simulations (e.g. CFD) depending on the candidate's background and interests.
