摘要

作者提出了一个数值模型来模拟导管注射过程中发生的主要物理过程:用Navier-Stokes方程考虑血液动力学，用平流扩散方程考虑血流中物质的分散。该模型再现了体外观察，并允许人们在不同的流动条件下评估各种导管设计的一些混合特性。

Study of catheter designs for infusion procedures using numerical simulations

The authors propose a numerical model to simulate the main physical processes occurring during catheter injection: blood dynamics is taken into account with the Navier-Stokes equations and the substance dispersion by the flowing blood with the advection diffusion equation. The model reproduces in vitro observations and allows one to evaluate some mixing properties of various catheter designs in different flow conditions.
