SediSound: Novel acoustic instrumentation for quantifying and characterising multiphase flows

该项目将开发和测试一种新的仪器，能够同时测量多相流体流动的流速、悬浮泥沙浓度和粒度，并在多个维度上进行高时间分辨率的测量。现有的商业上可用的仪器允许在一个点或小剖面上量化多维速度，其他商业上可用的仪器允许量化悬浮沉积物和粒度剖面，但没有商业上可用的仪器允许同时测量多维速度和沉积物剖面。这种仪器的开发将导致一系列环境和工业两相流中关键过程的量化发生阶级性变化，包括负责驱动河流和沿海环境中沉积物的侵蚀、运输和沉积的湍流剪切应力的量化，以及一系列工业流动过程和水处理设施中的流动过程。因此，这种工具将具有广泛的用途和重大的商业潜力。该计划的工作将设计、构建、测试和验证运行仪器所需的硬件和软件。作为正在进行的ERC整合项目的一部分，测试结果将针对一套现有的仪器进行基准测试和每个组件测量。PoC还拥有一个嵌入式开发人员（Ubertone），拥有强大的知识产权协议，以及参与原型测试阶段工作计划的最终用户合作伙伴，他们共同为开发的新技术提供并开发出通往市场的途径。

This project will develop and test a new instrument capable of simultaneously measuring the flow velocity, suspendedsediment concentration and grain size of multi-phase fluid flows across multiple dimensions at high temporal resolution. Existingcommercially-available instruments permit the quantification of multi-dimensional velocities either at-a-point or over smallprofiles and other commercially-available instruments permit the quantification of suspended sediment and grain sizeprofiles, but no commercially-available instrument permits the simultaneous measurement of both multi-dimensional velocityand sediment profiles.The development of such an instrument will lead to a step change in the quantification of key processes within a range ofenvironmental and industrial two-phase flows, including quantification of the turbulent shear stresses responsible for drivingerosion, transport and deposition of sediments in riverine and coastal environments through to flow processes in a range ofindustrial flow processes and water treatment facilities. Such an instrument will therefore have wide utility and significantcommercial potential. The work within the programme will design, build, test and validate both hardware and the softwarerequired to run the instrument. The results will be bench-marked and tested against a suite of existing instrumentation foreach of the component measurements as part of the ongoing aligned ERC Consolidator Project. The PoC also has anembedded developer (Ubertone) with robust IPR agreements in place, and as well as end user partners involved in theprogramme of work in a prototype testing phase, which together provide and outcome the development of a pathway tomarket for the new technology developed.
