Investigation of the Flow Separation from the DrivAer Notchback Rear Window with DDES and LES Luca Bauer (Technical University of Munich)･Jonas Sebald (Audi)･Philipp Schlichter･Thomas Indinger (Technical University of Munich) Computational Fluid Dynamics (CFD) workflows that employ Delayed Detached Eddy Simulation (DDES) typically provide accurate predictions regarding automotive external aerodynamics. However, DDES can exhibit inaccuracies in specific regions of the flow field. This study examines one such critical area: the boundary layer separation from the rear window. Therefore, we benchmark both DDES and Large-Eddy Simulation (LES) against wind tunnel data for the DrivAer Notchback by using an OpenFOAM workflow. |

Numerical Investigation of Water Flow in Narrow Gaps of Vehicle Interior Components Evelyn Sabella Rugerri (Technical University of Munich)･Dirk Baeder (Audi)･Thomas Indinger (Technical University of Munich) If one unintentionally spills beverages or keeps the sunroof open during a rainy day, several electronic and mechatronic components may be exposed to water. Hence, monitoring water in vehicle interior is part of a growing body of research on water management. This study bridges the physical insights to its virtual representation using a novel Lagrangian 3D-CFD solver. Despite its flexible nature, the computational time for simulation on complex geometries still seeks great optimization. This is to be conducted by means of a mathematical modeling of flows in narrow gaps, whereas the models are obtained empirically using Design of Experiment (DoE). |

Numerical Implementation of a Leak Testing Method to be applied to High Voltage Batteries Matthew Sleight･Stefan Adami (TUM)･Mathieu Mulmann (Audi)･Thomas Indinger (TUM) The production of High Voltage batteries is a major challenge for the automotive industry. To improve battery production quality, optimizing the leak test would be an important development. This test consists of changing the pressure in the battery and measuring the volume leakage. To do this, CFD simulations are carried out using the SPH method. A numerical model is used to reproduce the different phases of this test. These results are compared with experimental data. The recreated process will help to optimize the process thanks to a better understanding of the phenomenon. |
