摘要
大 Knudsen 数条件下,从气溶胶粒子的动力学参数入手,求得了全域 Péclet 数下的碰并率通量结果.讨论了表面性质对气溶胶粒子碰并率的影响,指出只要势力存在,在粒子半径空间总会存在一个 Brown 占优的区域.同时也讨论了密度比对气溶胶粒子碰并率的影响,指出可以在碰并率极限处使用可加性假设,使用上下游的说法更加适合描述该情况下的碰并率.
At large Knudsen number, through the dynamics parameters of Aerosols, the flux of coagulation rate is gained in all Péclet number. The infection on coagulation rate is discussed. If the force exists, there must be an area where the Brown action is dominant. The density ratio on coagulation rate is discussed too. The thesis points out that additional hypothesis can be used at the inflexion of coagulation rate, which should be better described with upstream and downstream on that condition.
