|Pulse wave Propagation in Arterial Networks|| Jordi Alastruey, Kim Parker, Joaquim Peiro, Spencer Sherwin, Peter Weinberg
Pulse wave propagation in arterial networks is studied using the 1-D equations of blood flow in compliant vessels, which are solved using a discontinuous Galerkin scheme.
|Mixing in Helical Bypass Grafts|| Andrew Cookson, Spencer Sherwin, Denis Doorly
To investigate the fluid dynamical properties of helical pipes, particularly from a mixing perspective, in order to quantify and understand their potential for use as artery bypass grafts and arterio-venous shunts

The long-term success of arterial bypass grafting with autologous saphenous veins is limited by neointimal hyperplasia (NIH). Placement of a loose-fitting, porous stent around end-to-end, or end-to-side, autologous saphenous vein grafts has been found significantly to reduce NIH, but the mechanism is unclear.
|Computational Fluid Models for Anastomoses||
In this study a series of model anastomoses are considered under varying geometric conditions with symmetric and asymmetric inflow profiles.
|Geometric Characterisation of Peripheral Bypass Grafting||
Principal: Colin Caro, Nick Cheshire, Spencer Sherwin
Clinical: Jeremy Crane
Academic: Denis Doorly, Kyung Eun Lee, Sergio Giordana, Yannis Papaharilaou, Joaquim Peiro
In this study MRI imaging, duplex ultrasound and CFD are used to reconstruct the geometry and flow environment in in-vivo patients. The aim is to gain an indication of the influence of graft geometry and the associated flow on the development of vascular disease.
