The collision momentum of condensed particles has little relation with the injection nozzle configuration under the same primary nozzle equivalent diameter. 在相同的一次喷嘴当量直径条件下,凝相颗粒的碰撞动量与喷嘴结构之间的关系不大。
At the same time, according to evaluation criterion of head wound, the collision speed, collision angle, collision mass, head diameter, thickness of structure to be impacted and the effect of collision position on head wound are analyzed. 同时依据头部损伤的评价标准,分析了碰撞速度、碰撞角度、撞击质量、头部的直径、被撞结构的厚度以及撞击的位置等对头部损伤的影响。
The results show that the simulation results of droplet collision model are influenced by the calculation conditions, such as grid size, time step, number of particle stream and initial droplet diameter. 发现计算网格尺寸、时间步长、颗粒流数量及初始液滴粒径等因素均对液滴碰撞模型有明显影响。
