Flows in Rigid and Arterial Graft Bifurcation Modelsoved, arterial grafting has become a frequently performed and generally successful operation. Despite the broad experience and the high degree of success, many problems still remain; in particular, the mechanism of formation of the atherosclerotic lesions and the behaviour of the vascular flow after

A Predictive Scheme for Flow in Arterial Bifurcations: Comparison with Laboratory Measurementsh finite element grid definition and finite difference solution methods. Results are compared with laboratory measurements of Ku and Liepsch for T-junctions. Comparison is excellent for two-dimensional steady flow tests, and very good for three-dimensional pulsatile flows.

Modelling the Pulmonary Circulation in Health and Diseaseventilated under steady conditions, and pressure-flow characteristics measured. The purpose of these experiments is to assess the gross hæmodynamic effects of mechanical blockage and of some vasoactive compounds. Pulmonary hypertension, which may occur as a result of various initiating factors, resu

Numerical and Experimental Investigation of Lung Bifurcation Flowsof a network of bifurcating tubes through which air flows from the trachea through 17 generations of airways where convective processes dominate to the 6 further generations (alveolar zone) where gas exchange occurs and where transport is dominated by molecular diffusion. The part of the lung studie

Zusammenfassung und Implikationen,tery bifurcation it is concluded that curvature effects indeed play an important role in the daughter branches of this bifurcation, but also that the local geometry of the carotid sinus highly affects the axial and secondary flow fields. In general a good agreement is found between the numerical and experimental results.
