Balance-Characteristic Method for Calculating Hemodynamics
of a Single Vessel
摘要
Abstract
The paper is devoted to constructing a numerical algorithm for calculating the blood flowin a volume vessel. A system of differential equations describing the dynamics of fluid in a singlevessel with moving walls in cylindrical coordinates is derived assuming axial symmetry inarbitrary Eulerian-Lagrangian variables. A balance-characteristic scheme based on the Cabaretmethodology is constructed for the obtained system of equations. The results of calculations oftest problems are given.
