03.1 - Aerodynamics - CFD Methods and ValidationAERODYNAMIC EVALUATION OF THE EXTERNAL FLOW OVER PICKUP TRUCKSE.-K. Mascia¹, O. de Almeida¹; ¹Federal University of Uberlandia, Brazil The computational analysis of the external flow over automotive vehicles is increasingly important in the automotive industry since it provides consistent and reliable results which enable significant improvements in new products. In this context this work proposes an aerodynamic evaluation by numerical modeling of the external flow over notchbacks and pickups trucks. As a tool in engineering it is proposed the use of an open source code OpenFOAM for the qualitative and quantitative analysis of the flow over the Ahmed body and DrivAer models. Different meshes and numerical methods were evaluated – RANS (Reynolds Averaged Navier-Stokes) and DES (Detached Eddy Simulation). The results were compared to experimental measurements and literature data in order to validate the numerical approach to be applied in future vehicle aerodynamics analyses. |
