I am currently attempting to model the absorption of Carbon Dioxide by different solutions. I found this paper that does this. They used Comsol Multiphysics but show almost no images of them modeling things in Comsol. They only show the differential equations used.
Did they find these equations from scratch and input them into Comsol or did they just use the modeler and the physics?
How would I go about figuring out the procedure they did the experiment in if they did use the model builder and the physics plugins?
