Effect of Vortex generators on Aerodynamics of a Car: CFD Analysis
نویسندگان
چکیده
Flow separation at the vehicle’s rear end is the major cause of an aerodynamic drag in a car. In order to delay the flow separation at the rear, bump-shaped vortex generators at the roof end of a car are tested in this paper for two different types of car models Sedan and Hatchback. The aerodynamic analysis is carried out using GAMBIT and FLUENT for Sedan and Hatchback models. Vortex Generators are found to be not very sensitive for the designing parameters. CFD analysis confirms that the use of Vortex Generators reduces both the drag and lift coefficients.

In this paper the effects of rigid triangular passive vortex generators on a hydrofoil were investigated numerically. In the first step using the Finite Volume Method the bare hydrofoil were modeled and the results of lift and drag coefficients were validated using experimental data. In the next step the hydrofoil armed with vortex generators was modeled and its effect on the hydrofoil perfo...

The horseshoe vortex generated around the sail-body junction of a submarine has an important influence on the uniformity of the submarine wake at the propeller and hydrodynamic noise. The influence of the horseshoe vorex on the submarine performance is not negligible. A suitable way to reduce the effects of this separated flow is to use vortex generators. The main goal of the present study is t...

Separation of suspended droplets in a fluid flow has been a great concern for scientists and technologists. In the current study, the effect of the surface roughness on flow field and the performance of a gas-oil cyclone is studied numerically. The droplets and the turbulent airflow inside the cyclone are considered to be the discrete and continuous phases respectively. The Reynolds stress mode...
