| Abstract: | The paper introduces the application of laser sheet technology and laser doppler veiocity meter to study the streamline of three dimensional separating flow of car wake and to measure the distribution of velocity.The experiment results show that it is effective,by combining the method of laser flow visualization and the digital imaging technology,to reveal the structure of the car wake and to determine the resource of drag.This paper provides the foundation to establish the theoretical model of dynamics stimulation of three dimensional separating flow of the car. |
