摘要
用UG对一流线型轿车进行了三维实体建模,将其导入前处理软件Gambit,建立计算域后网格化,并用CFD软件FLUENT对汽车模型的外流场进行了三维稳态流动数值模拟,得出了汽车模型的三维速度场和压力场,为获得最佳空气动力性的轿车设计提供了直观依据.
In this article,a three dimensional solid model of a streamlined car is established by using Unigraphics,the model is imported pre-processing software Gambit,then the computing domain is gridded.Three-dimensional numerical simulation of steady out flow was carried for the car modelwith the CFD software Fluent.The three-dimensional velocity and pressure field for the car model is obtained.It provides a visual basis to get the best aerodynamic design of cars.
