Applications and test cases

Abstract

Although medical imaging can provide relatively accurate geometric data of in vivo bypass grafts, as will be discussed in Section 12.1.2, to obtain an understanding of the general flow features it is instructive to consider an idealisation of a distal bypass graft. In this example we therefore consider the problem shown in Fig. 12.1, which consists of three vessels, all of the same diameter D, where the bypass (connecting) vessel has a centreline length of 3D and the host vessel is represented by two co-aligned vessels of lengths 5D (distal) and 10D (proximal) from the junction.
