http://matlab.cheme.cmu.edu/2011/11/17/modeling-a-transient-plug-flow-reactor/#comment-5855807335<p>I'm also asking exactly the same question. The problem when two reactants are used is that the vectorization as shown doesn't work since C(i) is the concentration over the length of the reactor instead of that representing type of reacting species.</p><p>Could someone, since it appears that Prof. Kitchin is no longer active in this page, shed a light on how to solve the problem, that is, how to represent the vectorization for multiple species?</p>lontongstroongThu, 12 May 2022 21:08:12 -0000Re:

http://matlab.cheme.cmu.edu/2011/11/17/modeling-a-transient-plug-flow-reactor/#comment-4771656578<p>you are probably trying to solve a system of ODES.

http://matlab.cheme.cmu.edu/2011/11/17/modeling-a-transient-plug-flow-reactor/#comment-4771246967<p>Hello, I am currently working in modelling a PFR in a water treatment plant for an university project and I am working with to substances substrate and biomass, so I need to solve two differential equations. I was using your program but I do not know how can I implement it to solve the second differential equation. Do you know if it is possible to do. thanks</p>Franklin GarciaSat, 25 Jan 2020 22:51:46 -0000Re:
