| 摘 要： | 本文采用球形刚性颗粒悬浮于牛顿流体的血液模型，基于有相间滑移的两相流动层流Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，采用相间滑移算法（Ｉｎｔｅｒ－ＰｈａｓｅＳｌｉｐＡｌｇｏｒｉｔｈｍ）对圆管内定常轴对称血液入口两相流动问题进行了计算，获得了与实验结果吻合的计算结果，较好地模拟血液流动中红细胞的径向迁移现象，结果表明，采用二相流动模型研究血液流动是一种有前途的方法。

| Abstract: | The phenomena of radial migration are the most important in the flow of small blood vessels. Inthis paper, a rigid spherical particle suspension model, which is based on continuum medium theory,is adopted. The full laminar Navier-Stokes equations with interphase slip are used. Axisymmetricsteady of two phase entrance flow in a horizontal straight tube is solved by using Spalding's inter'Phase Slip Algorithm (IPSA). Results show the two phase flow model is good for demonstrating thecharacteristics of the radial migration of red blood cell in blood flow, and IPSA method is very effective for solving the problem of two phase flow. |
