Abstract

in order to study the survival time of the water mist, the quality, energy and motion models were established by using mathematical methods, and then the three models were integrated by fourth-order Runge-Kutta method; at last, by analysis of simulation data, the conclusion were obtained that the survival time of the droplet had been related the particle size and ambient temperature, and their running distance had been related to the particle size and initial velocity.
