차량 성능 개선을 위한 OSRVM의 최적 형상 연구

This study investigates the effects of OSRVM configurations such as bezel, stalk lengths, and head planview shape, etc. on the aerodynamic performance of the passenger car. In order to validate the flow solver, FLUENT which is a very well-known commercial code, the flow field around an Ahmed Body was analyzed numerically and compared with the experimental data. The predicted aerodynamic performance shows a good agreement with the experimental data. In the present paper, two parameters, which are the bezel and stalk length, are considered and presented. The other parameters will be studied in the near future.
