| Abstract: | The experiment of this paper is done with a constant volume chamber. A high speed CCD video camera was used to grab diesel sprays in three working conditions. The back pressures of the experiment are 0.1 MPa, 0.7 MPa and 1.05 MPa. The grabbing speed of the CCD video camera was set at 40 500 frame per second. The digital image processing technique was used to sharpen the edge of the spray images. Three tip penetrations of the sprays were showed quantitatively. Some experimental problems, such as the open time of the three way valve and time serial etc., were analyzed. |
