Abstract
The aerodynamic characteristics of the vehicular profiles have grown more concentration as it has influence on fuel consumption, comfort, and driving characteristics. The objective of the current work is to study the aerodynamic characteristics investigations of BMW M6 and AUDI R8 using both experimental and computational approaches. The computation analysis was done using the models developed using FREE FORM SCULPT module in AUTODESK FUSION 360. The airflow around a model is analyzed by AUTODESK FLOW DESIGN-VIRTUAL WIND TUNNEL software to assess the drag force, drag co-efficient and interacting flow fields. The drag force is also calculated analytically for the two cars and was found to be in good agreement with the computational results. The prediction of experimental aerodynamic characteristics is done by conventional wind tunnel approach. The experimental investigations were done on an open-loop suction-type wind tunnel having a 30 cm × 30 cm × 100 cm test section. The 3D prototype of reduced scale (1:15) of the two car models was developed using the 3D printing machining from generated software models. The computation results were found to be validated by the experimental results by the wind tunnel method.
