Simulate in comsol or matlab and get the results.

 I have attached a copy of my article on computational fluid dynamics model of CO2 capture in fluidized bed reactors. 

simulate what ever they have done in the given paper either in comsol or matlab and get the results. Equations are missing in the article, so try to get those equations in your way. for your reference just go through 2.2 in the attached article.

secondly, write a report on how you simulated and got the results.
