摘　　要：基于多孔介质理论和流体力学理论,建立了磁性纳米粒子在渗透壁微血管中的流体模型。与将粒子视为连续介质的NP(nernst-planck)模型相比,摒弃了粒子连续介质假设,将粒子视为离散粒子。模型考虑磁性纳米粒子的分布为Maxwell分布,根据Navier-Stokes方程、体积方程和达西定律,预测了微血管中的压力分布和流体的运动,分析了壁面渗透效应对微血管中流体的影响。Based on the porous media theory and fluid mechanics theory,this pape establishes fluid model of magnetic nanoparticles in permeable wall of capillaries. Compared to NP model（ Nernst-Planck）,while considering particles as continuum,the particle continuum hypothesis is abandoned in the model with,the particle as discrete particles. In this model,the magnetic nanoparticles distribution is considered as Maxwell,according to the Navier-Stokes equation,volume equation and Darcy＇s law,the local pressure distribution and liquid field velocity can be predicted and the influence of the wall penetration effect of capillaries on the distribution of fluid is analyzed.
