โฆ Synopsis
This work is aimed at developing efficient computational algorithms for numerical simulation of steady-state incompressible vis-sional (or ''integral'') models of the whole cardiovascular cous flows in nodes of circulation networks. High order accuracy circulation network take into account the mutual interacimplicit stabilization algorithms based on upwind finite-difference tion of all components of the network, but they are incapaschemes were proposed. In order to treat complicated geometry, ble of providing any data on the fluid flow structure, except decomposition of computational domains was used. The effect of the distribution of averaged pressure and mass flow rate an external circulation network was simulated by means of nonlocal boundary conditions linking inlet and outlet flow parameters. A along the network (see, for example, [19]). fluid flow related to specific cardiovascular operation was studied
In this work an attempt to combine a global hydraulic numerically as an example. แฎ 1997 Academic Press model of a circulation network with a detailed Navier-Stokes simulation of flow in a pipe junction was undertaken. In order to attain the aim, we proposed using one-62
