Abstract: ased on analysis of experimental results on the droplet velocity and flying angle in initial region of water sprays, aspects of initial condition are studied in details, and three ways of treating initial condition, the statistical, the stochastic and the conventional ones respectively, are presented from the experimontal results. The spray motion is then calculated by use of numerical method for the two-phase flow, and the effect of different treating methods to deoplet initial condition on computational results is studied. The calculated and the experimental results are compared with eath other, and they are in good agreement.
