Webb16 apr. 2024 · Although I guess that there are bounds on P and T, here is a code that will give you a start. In case you want to constrain P and T, use "fmincon" instead of "fminsearch". Theme Copy function main format long T = 300; P = 1; x0 = [T P]; options = optimset ('MaxFunEvals',100000,'MaxIter',100000) x = fminsearch (@fun,x0,options) end The plug flow reactor model (PFR, sometimes called continuous tubular reactor, CTR, or piston flow reactors) is a model used to describe chemical reactions in continuous, flowing systems of cylindrical geometry. The PFR model is used to predict the behavior of chemical reactors of such design, so that key reactor variables, such as the dimensions of the reactor, can be estimated. shannice wilner

"Webb6 mars 2013 · Modeling a transient plug flow reactor. The PDE that describes the transient behavior of a plug flow reactor with constant volumetric flow rate is: ∂ C A ∂ d t = − ν 0 ∂ C A ∂ d V + r A . To solve this numerically in python, we will utilize the method of lines. The idea is to discretize the reactor in volume, and approximate the ... " - Simulation pfr
