Mixing in stirred vessels is a key unit operation in many engineering operations, and is of particular interest to Syngenta, but also across numerous industries, and has motivated many studies aimed at understanding a range of phenomena as a pathway for optimising relevant processes [1-3]. Understanding the key transport phenomena in these processes relies on appropriately scaled-down mixing experiments, and excellence in scale down, in turn, requires properly sized vessels and selected fluids and operating conditions.Measurements of such phenomena can be performed using different approaches. Corporate laboratories focus on measurement robustness, speed, reliability, cost and safety, while university best-practice is concerned with novel methods that can inspect such flows at a level of detail that is currently unattainable in industry, thus providing new information and a much-improved level of understanding. The overall aim of this present project is to apply advanced measurement techniques to a selected flow of interest, and to use the resulting data to interpret and comment on current industrial knowledge and practice. Of interest, as noted earlier, are flows in stirred vessels in the present of interfaces (bubbles or droplets) and heat/mass transfer

在搅拌容器中混合是许多工程运营中的关键单位操作，并且在许多行业中也特别感兴趣，并且促使许多旨在理解一系列现象的研究，作为优化相关过程的途径[1-- 3]。了解这些过程中的关键运输现象依赖于适当缩小的混合实验，而卓越的规模降低则需要适当尺寸的容器，选定的流体和操作条件。这种现象的测量可以使用不同的方法进行。公司实验室专注于测量鲁棒性，速度，可靠性，成本和安全性，而大学最佳实践却关注新的方法，这些方法可以在行业中以目前无法实现的细节进行检查，从而提供新的信息，从而提供新的信息，并提供新信息提高了理解水平。本项目的总体目的是将高级测量技术应用于选定的感兴趣流，并使用结果数据来解释和评论当前的工业知识和实践。如前所述，感兴趣的是在接口（气泡或液滴）和热量/传播的搅拌容器中的流动
