| Abstract: | To analyze the flow fields of an electric driven vehicle with in-wheel-motor, the computational results of flow fields were obtained with front end airflow simulation, so the external flow around the wheels of an in-wheel-motor vehicle in detail conditions was obtained. At the same time, the results of an in-wheel-motor vehicle and a conventional vehicle were compared for local and global flow fields. Furthermore the ventilation of in-wheel-motor system was annlyzed, providing aerodynamic data for thermal dissipation of brake and in-wheel motor. |
