Assessing Eulerian Indicators for Predicting Mixing in A Blinking Vortex System with Varying Degrees of Continuous Transition
A discontinuous change in sequential velocity fields is known to generate laminar flow mixing through the mechanism of streamline crossing. However, previous research has suggested that a small degree of continuous transition...
Normal fluid stresses are prevalent in rotary ventricular assist devices
Despite the evolution of Ventricular Assist Devices (VADs), VAD patients still suffer from complications due to the damage to blood by fluid dynamic stress. Since rotary VADs are assumed to exert mainly shear stress, studies of...

Influence of shear-thinning blood rheology on the laminar-turbulent transition over a backward facing step
Cardiovascular diseases are the leading cause of death globally and there is an unmet need for effective, safer blood-contacting devices, including valves, stents and artificial hearts. In these, recirculation regions promote...

Abstract: Bayesian optimisation is a sample-efficient search methodology that holds great promise for accelerating drug and materials discovery programs. A frequently-overlooked modelling consideration in Bayesian optimisation...
Efficiently Generating Mixing by Combining Differing Small Amplitude Helical Geometries
Helical geometries have been used in recent years to form cardiovascular prostheses such as stents and shunts. The helical geometry has been found to induce swirling flow, promoting in-plane mixing. This is hypothesised to...
