Description A recent report indicates that UK fluid dynamics contributes £14billion to the UK economy. Understanding fluid rheological properties and their underlying structure is key in most fluid applications. A rheometer is an instrument that typically allows probing the bulk response of fluids when submitted to an applied stress. Often visual inspection of the sample structure during rheological experiments reveals important insights about material behaviour under flow. In this project, you will design (and build) an experimental set-up to adapt a commercial shear rheometer available in our labs to allow for flow visualization in situ while simultaneously measuring the rheological properties. Key Objectives Perform a review on the topic and examine the different options available commerciallyLearn how the rheometer operates and the basics of microscopyPropose a new and adequate design/set-up (or update a previous version), including mechanical stand, optical path and control systemsBudget all the necessary partsDepending on time/budget constraints build and test the proposed set-up.
