荷电雾滴上粉尘粒子的扩散沉积

The diffusional deposition of particles on a charged droplet

采用浓度边界层理论讨论了细微粒子在荷电雾滴表面上的扩散效应。根据雾滴前向驻点处有限直径粒子的沉积行为分析了雾滴与粒子间的静电作用对小粒子捕集效果的影响。

The diffusional deposition of particles of finite diameter on the surface of a charged droplet is estimated by employing thin concentration boundary layer theory. The mass transfer rate at the forward stagnation point of the droplet is derived to show the effect of electrostatic forces on the collection of submicron particles.
