Numerical Simulation on Flow Field of Vehicle Rear Spoiler

Select a Chinese self-developed vehicle as research subject, according to the need of study, it simplifies the vehicle shape appropriately, uses CATIA to establish 3d model, uses the software of HyperMesh to genetate mesh according to tetrahedron and hexahedron mesh program, and simulates the CFD of the vehicle and rear spoiler by CFD software of STAR CD, The simulation result show that increase the rear spoiler helps to reduce the lift of the rear vehicle, avoid the negative factors of reduced adhesion of the rear wheel and low high-speed stability etc. to a certain degree.
