分叉与网状血管中血流的一种计算机模拟分析

目的用一种可视化模拟计算工具来模拟分析分叉与网状血管的血流。方法采用有限元技术和JAvA语言编制程序用于计算典型的分叉与网状血管模型。结果模拟计算人脑Willis环的血流与文献结果一致，表明用该方法能直观地建立血管模型，输入血管参数和边界条件，结果可通过图形显示或直接输出数据，为基础研究和临床应用提供参考依据。结论这种方法可以方便地建立、修改模型来模拟心血管系统的非正常情况，比如低血压、高血压、血栓、出血等。

A Computer Simulation and Analyse of Blood Flow at the Branch and Network of Blood Vessel

Objective This paper furnishes a simulation tool for blood flow in the branch and network of blood vessel. It supplies references for fundamental research and clinic application. Methods Finite-element model and JAVA language are used to compile computer program of simulating blood flow in the branch and reticulated blood vessel. Results The program can construct vessel model, input blood vessel parameters and deal boundary condition. Computer data can be presented by output directly and figure display. The results are verified. Conclusion The method can conveniently build and modify model to simulate cardiovascular abnormalities, such as hypotension, hypertension, stenoses and haemorrhage.
