首发时间:2008-01-25
摘要:本文应用ANSYS中的CFD功能建立了基于计算流体力学的国产三厢轿车外流空气动力特性有限元计算模型,采用有限体积法求解三维定常的不可压缩N-S方程,实现车身外流场三维数值模拟,得到了车身外流场的速度、压力、涡流的分布,为轿车车身设计提供了参考。

The Numerical Simulation on 3-D Outer Flow Field around Car based on ANSYS
Abstract:The aerodynamic FEM model of China-made three pack passenger car body based on CFD was established by the CFD of ANSYS, the finite volume method is used to solve 3-D steady incompressible N-S equation, The numerical simulation on 3-D outside flow field of the body was obtained, including 3-D velocity field, 3-D pressure field and turbulent flow field, which provides reference for the car body design.
Keywords: CFD Aerodynamic characteristics Numerical simulation
