摘　　要：利用UG对某一微型轿车进行三维实体建模,将其导入前处理软件Gambit,建立计算域后网格化。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,为获得最佳的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 Mini Car is established by using Unigraphics.First,the model is imported for pre-processing by software Gambit,then the computing domain is gridded,and three-dimensional numerical simulation of steady flow was carried out for the car model by using CFD of software Fluent.At last,the three-dimensional velocity and pressure field for the car model are obtained.The approach provides a visual basis for the best aerodynamic design of cars.
