Abstract :
To save energy and to protect the global environment, fuel consumption reduction is primary concern of
automotive development. In vehicle body development, reduction of drag is essential for improving fuel
consumption and driving performance, and if an aerodynamically refined body is also aesthetically
attractive, it will contribute much to increase the vehicle’s appeal to potential customers. However, as the
passenger car must have enough capacity to accommodate passengers and baggage in addition to minimum
necessary space for its engine and other components, it is extremely difficult to realize an aerodynamically
ideal body shape. The car is therefore obliged to have a body shape that is rather aerodynamically bluff, not
an ideal streamline shape.
One way to overcome drag is to generate vortex flow at the rare end of the vehicle using vortex generators,
reduction of drag in automobiles with vortex generators is already proved working in some previous studies,
but no standard geometry is specified for the vortex generator. In this project we are going to compare the
performance of different geometry’s of vortex generators using Ansys 15.0 fluent workbench, all the 3d
models of vortex generators are developed in Catia v5 software.
