摘要
在求解雷诺平均三维不可压Navier-Stokes方程的基础上采用虚拟现实技术建立了虚拟汽车风洞。虚拟汽车风洞与传统的CFD计算结果可视化的表现手段相比,能够交互式地从各个不同的位置更形象更直观地观察车身外流场的流态。采用这种方法可节省汽车模型制作和风洞实验的巨额资金,缩短新车型的开发周期。
Based on the solution by CFD technique for the Reynolds averaged incompressible Navier-Stokes equation of 3D turbulent flow around a car body, virtual automobile wind tunnels are built by virtual reality technique. The virtual automobile wind tunnel can present external flow field around a car body in a more objective way than previously used CFD visual technique can, thereby realizing a cost savings and shortening development time.
