带电雾滴速度场理论研究

THEORETICAL RESEARCH ON THE VELOCITY FIELD OF CHARGED DROPLET

从理论上建立了气流与带电雾滴速度关系式。由欧拉法和拉格朗日法建立了确定性带电雾滴速度场、带电雾滴速度驻值线方程和由随机微分理论建立的带电雾滴速度随机模型,使两相流动有了初步的理论模型,还建立了喷头结构参数和雾滴速度关系式,将为控制流场和选择合理的喷头参数提供依据。

In this paper, The relationship between the airflow and the velocity of charged droplet was founded theoretically. The definite charged droplet velocity field and the velocity static equation were obtained by Euler method and Lagrange's method and the random model of charged droplet velocity was obtained by random differential theory. Thus two-phase flow has its initial theoretical pattern. On the other hand, the equation for parameters of nozzle and droplet velocity will contribute to controlling flow field and selecting suitable nozzle parameters.
