課程概述 |
氣膠學
本課程主要使學生了解懸浮於空氣中之固體、液體微粒之物理特性（包括：大小分布、形狀、吸光、散光及荷電），運動特性（包括：直線、曲線運動、擴散凝聚、沉降）採樣與監測，及各種粒狀物控制之基本理論，本課程除可應用於空氣污染之基本理論外，尚可應用於無塵室之粒子控制。（半導體）視程研討，（氣象），噴霧乾燥（奶粉、瓷磚）乃至國防工業（彈道之修正）等。上課為課堂講演。
教科書：
（1）、Parker C. Reist Introduction to Aerosol Science
（2）、Hinds Aerosol Technology。 |

課程目標 |
1. Introduction to aerosols: climate effects, health effects, concentrations, and size distributions.
2. Movement of particles in air: diffusion, friction coefficient, external force fields.
3. Transport/removal processes for particles: external force fields, efficiency of filters.
4. Transport/removal processes for particles: stop distance, impaction efficiencies
5. Coagulation of particles: effects of Brownian motion, shear flow, turbulence, and gravity.
6. Review of thermodynamic principles for condensation; Kelvin effect.
7. Secondary particle formation: homogeneous nucleation, heterogeneous condensation.
8. Visibility: absorption vs. scattering of light, extinction coefficient, examples of measurements.
9. Processing/ alteration of airborne particles in urban environments |
