Abstract: Numerical simulation and analysis of fluctuating pressure on outside surface around model was conducted using large eddy simulation of soft ware Fluent. It is obtained that the scattergram of fluctuating pressure on outside surface of high-speed automobile. The result shows that the scattergram of fluctuating pressure by large eddy simulation coincides with the test results. It can be concluded that the calculations are available for project but the precision of simulation need be improved.

Key words: high-speed automobile, fluctuating pressure, large eddy simulation

摘要: 应用软件Fluent的大涡模拟方法,对汽车模型的表面脉动压力进行了数值模拟与分析,得到了高速车辆的侧表面脉动压力分布图。结果表明,大涡模拟脉动压力分布趋势与试验结果较为吻合,计算结果基本满足工程需要,但计算精度有待于进一步提高。
