| Abstract: | The paper introduced the experiment of using laser-sheet technology and laser-Doppler-anemometer to study the streamline of 3D separating flow at car' s wake and to measure the distribution of velocity. The results show that it is effective, by combining the laser flow visualization and the digital-image processing technology, to reveal the structure of car's wake and to determine the source of drag. This study provides a foundation to establish the theoretical mode of dynamic stimulation for 3D separating flow around the car. |
