| Abstract: | The atomization behavior of the fuel injector in engine was obtained by the measurement of the fuel particle field by using phase doppler particle anemometer(PDPA) and laser holography technique.The principles and condition of two measurement methods were introduced in this paper.The results from laser holography measurement were given and compared with PDPA technique,which shown that the laser holography method is precise.Moreover,the particle field of fuel injector was measured in wind tunnel. |
