Study on Mathematical Model of the Oil Droplets Collision in the Flat Board

基于油滴几何轨迹交叉来认可油滴发生碰撞建立了描述液滴间碰撞的数学模型,为油滴间的碰撞提供判断依据,来弥补迄今为止几乎没有可用数据来表示油滴碰撞时间的关系式。其计算结果与采用PDM数值模拟计算结果相吻合,验证所建立的油滴碰撞模型具有一定可靠性。

Based on mathematical model of the oil droplets collision is set up according to the cross of geometric trajectory. This modal pro- vides a reference for judging oil droplets collision which can remedy for lack of equations that can be used to express the oil droplets colli- sion time by statistics. And the calculated results are identical with the simulation results by PDM. The established model of off droplets collision proves to have some reliability.
