FLOW ANALYSIS OF OVERTAKING VEIDCLES: CFD STUDY

The aerodynamic forces occurring when one road vehicle overtakes another are to
be investigated using two-dimensional (2D) computational fluid dynamics. Although a
lot of researches have been carried on the aerodynamics of the flow of overtaking
vehicles, very little information is available on flow around full scale vehicles. Increasing
the size of models I 0 times would results in the increase of the mesh size, making it more
expensive and requires higher performance hardware. This research studied the
aerodynamic forces by the quasi static approach using CFD analysis; it also laid the
grounds for further transient and 3D investigation on the full scale model and discussed
their feasibility.
The purpose of this report is to discuss the outcomes of my final year project with
some guidance on how to reach these results for further investigations.
