1.光照强度耦合到化学反应可以参考博客(光强与温度的耦合,也可以继续耦合物质传递)://www.denkrieger.com/blogs/modeling-absorption-and-scattering-of-collimated-light
2.如果将溶液浓度视为均一溶液,可以不考虑污染物扩散迁移,但是物质反应后会影响C的浓度,会影响光的吸收率,可以考虑浓度对吸收率的影响。

对于催化剂的参数的辨识,可以通过实验去测试催化剂的阻抗谱等数据,然后通过参数估计对催化层反应动力学参数进行反演,具体可参考资料://www.denkrieger.com/model/electrochemical-impedance-spectroscopy-in-a-fuel-cell-218

反应速率表达式可以通过自定义的用户表达式来实现您所述的这种定义,即,输入一个基于浓度变量的计算公式。

您可通过第三方软件生成,或者使用 COMSOL 自带的随机函数功能实现,例如://www.denkrieger.com/blogs/how-to-generate-random-surfaces-in-comsol-multiphysics,//www.denkrieger.com/model/generation-of-random-surfaces-50281。
