根据课本和课件提供的公式和物理系数,画出S&P课本Figure13.A.2 (p.615)。即分别画出不同机制下(布朗碰并、切变碰并、重力沉降碰并),一个半径为1 μm的粒子与另一个粒子(粒径范围从小到大,自选范围)之间的coagulation kernel(K_{12}),并把总coagulation kernel(三个kernel之和)画出来。

其中,可假设collision efficiency 和 coagulation efficiency都是1。如果有兴趣,可参考文献自行增加考虑流体运动的复杂度。例如:加入随粒径变化的collision/coagulation efficiency。或可考虑不同温度梯度或水汽梯度下,热泳力或水汽泳力的影响等。

请说明你的额外考虑,并附注引用文献。
