SediSound: Novel acoustic instrumentation for quantifying and characterising multiphase flows

点击翻译按钮获取中文摘要

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.
