Drag Optimization of Multi-Axle Commercial Vehicle Model Using ANSYS Fluent

Aerodynamics is the study of the effects of air when in motion. The vehicle aerodynamics have become crucial since have realized its importance. This study has been focused on optimizing the aerodynamics with means of adding external aerodynamic component. A custom built multi-axle commercial vehicle (CV) model is subjected to aerodynamic modification and optimized. The components are modified to their optimum size, angle and shape to achieve the best to reduce the drag coefficient, and enhance better performance. The physical appearance of the custom built multi-axle commercial vehicle model has been given keen significance while designing the external devices. All the analysis and modifications have been tried out computationally in the CFD software “ANSYS Fluent” and the CAD modeling in “Creo Parametric”.
