This project is aimed at advancing the fundamental understanding of flow instability, the transition to turbulence and the effect on wall shear stress, in a dynamically constricted tube flow. The project will provide the first accurately resolved experimental flow analysis, using tomographic particle imaging velocimetry and 3D laser doppler anemometry, conducted on a novel experimental model, and will resolve, for the first time, turbulence characteristics of the dynamic constriction, using direct numerical simulation with a novel moving boundary implementation. The outcomes will provide the key link between fluid mechanics and wall shear stress, allowing future progress to be made in elucidating the causes of cardiovascular disease.

Optimising haemodynamics in complex stented arteries. This project aims to optimise the hemodynamics (blood flow) in coronary arteries with high curvatures and bifurcations. Experience has shown that the build-up of plaque — and the resulting occlusion of blood flow — tends to occur in these complex arterial regions. The most common therapeutic strategy is the insertion of a stent to prop open the artery. However, the nature of the geometry often leads to post-stenting complications such as rest ....Optimising haemodynamics in complex stented arteries. This project aims to optimise the hemodynamics (blood flow) in coronary arteries with high curvatures and bifurcations. Experience has shown that the build-up of plaque — and the resulting occlusion of blood flow — tends to occur in these complex arterial regions. The most common therapeutic strategy is the insertion of a stent to prop open the artery. However, the nature of the geometry often leads to post-stenting complications such as restenosis and thrombosis, ultimately resulting in negative outcomes. In this project, advanced research methods from fluid dynamics and optimisation and control will be used to potentially minimise these highly undesirable effects.Read moreRead less

This project aims to explore three human factor issues critical to the successful deployment of automated vehicles: factors influencing driver choice of automated vehicle control; interactions between automated and manually controlled vehicles; and driver detection, recognition, and reaction to automated vehicle system failures. Automated vehicles are predicted to be transformative, but their ultimate success and expected societal benefits will depend on drivers’ trust in them and on how people choose to use and interact with them. Insights from this research should prepare our society for more automated vehicles on the roadways.Read moreRead less
Investigating travel choice behaviour: a new approach. Since large monetary investments are involved in infrastructure decisions, it is of utmost importance that impacts of transport policies can be accurately predicted.
