Abstract: | The purpose of this study is to analyze the steady laminar blood flow through a complete idealized threedimensional bypass model with regard to the bypass hemodynamics and to compare the obtained results with the ones from the two-dimensional model. The type of flow restriction in the native artery is represented by either an occlusion or a 75% symmetric stenosis. In both cases, the blood is considered to be an incompressible Newtonian fluid. The walls are assumed to be impermeable and rigid. In order to solve the non-linear system of incompressible Navier-Stokes equations, the pseudo-compressibility method and the finite volume formulation of the central explicit fourth order Runge-Kutta scheme are applied using own computational software developed for unstructured hexahedral grids. |
