Best Practice Advice

Key Fluid Physics

The flow considered in the CFD-4D MRI comparison has to reflect some properties found in the cardiovascular system. Thereby it is necessary to consider a pulsatile flow, with intermediate values of the Reynolds number within the laminar-turbulent range. Furthermore the geometry also has to be representative to study typical flow patterns. The present geometry allows to study typical flow in aneurysm, arch, flow split and flow merge.
