摘要 采用数值模拟方法对典型钝头体模型二维半圆柱外绕流进行数值模拟,并将数值模拟结果与实验值进行对比、修正;再应用于人/椅救生系统外流场的计算,并对计算结果进行分析、讨论,提出系统设计时工程指导意见。 The paper uses the CFD method to simulate the flow field around the 2-D semicircle pillar,compare the simulative result with the experiment.The same method is adopted to simulate the flow field around the seat/occupant ejection seat system,then discuss the result.
