Bioengineering Seminar Series: "From Mixing to MRI: Numerical modelling in cardiovascular fluid mechanics", Dr Andrew Cookson, Kings College London

This talk on numerical modelling in bioengineering will consist of two parts.  The first covers doctoral research undertaken at the Department of Aeronautics, Imperial College London with Professors S.J.Sherwin & D. J. Doorly.  Motivated by the resrearch of Professor C. Caro, which suggests that the fluid mixing induced by helical geometries could prevent thromotic occlusion in coronary bypass grafts and arterio-venous shunts, we used spectral / hp element methods to investigate the fluid mechanical behaviour of small-amplitude helical pipes.  A particular focus of the work was to first characterise, and then devise strategies to optimise their mixing properties.

The second part concerns ongoing work conducted at the Department of Biomedical Engineering, Kings College London with Professor N Smith.  In this project we are developing finite element models of contrast agent enhanced MR imaging of myocardial perfusion, which is currently used at KCL to diagnose coronary artery disease.  Using a combination of subject-specific and idealised simulations, and working together with cardiologists, we aim to improve both the acquisition, and interpretation, of MR perfusion images.
