Modeling and analysis of vortex generator by using Computational Fluid Dynamic (CFD) on four wheeler vehicle
(FWV) model was carried out on this project. One of the main causes of aerodynamic drag for vehicle is the separation of flow
near the vehicle’s rear end.
To control the flow separation, Different shapes of vortex generator are test for application to the roof end of vehicle. A vortex
generator (VG) is an aerodynamic surface, consisting of a small vane that creates a vortex. The objective of the project is to
determine the drag reduction by using different VG, ranging from 60 km/h to 120 km/h that designed by Computational Aided
Design (CAD) in (CREO 2.O).
Vortex generator themselves create drag, but they also reduce drag by preventing flow separation at downstream. The overall
effect of vortex generators can be calculated by totaling the positive and negative effects. Drag force value can be obtained by
using CFX.
