Only when initial conditions were distributed. Inevitably, there will be a vety wide range of residence times for elements of fluid in the tank. The trajectories did show that the reactor was asymptotically stable over large variations in inlet parameters. A particular application is the use of the tank as a continuous stirred-tank reactor (CSTR). Please review the class example of TIS in page 48-51. Frequently, stirred tanks are used with a continuous flow of material in on one side of the tank and with a continuous outflow from the other.
All calculations performed with CISTRs assume perfect mixing. The behavior of a CSTR is often approximated or modeled by that of a Continuous Ideally Stirred-Tank Reactor (CISTR).
Transcribed image text: Problem 1: In the class, we intensively discussed the reactor equation of CSTR and CSTR in series (Tanks-in-series). It can be seen that an infinite number of infinitely small CSTRs operating in series would be equivalent to a PFR.
