Talk:Plug flow reactor model

From Wikipedia, the free encyclopedia

I agree that there are several issues with this page. At one point there is even confusion between a tube and a tank. The notation is truly ugly. Define your terms locally and use simple symbols. A universally applicable notation is an unrealistic goal. The citations are not the best choices. I do note that, contrary to the following comment, a PFR has zero axial mixing and complete radial mixing. Also, I would not introduce the unsteady state. Solutions are trivial for the constant density case unless you codger up some sort of feedback.

There are several issues with this article. PFRs do not have to be solved in a steady state fashion. Nor do they need to be solved for a single reaction, they can be solved for many reactions. The only assumption necessary is that there is perfect axial mixing of a differential volume and no interaction between individual volumes. The other assumptions are not key to the model, but only to the formulation of the quoted model. This is not to say that the assumptions might not simplify a problem drastically, just that they are not key. 60.241.185.216 10:24, 14 December 2006 (UTC)
