|Heat Effects 2 -- Effect of Parameter Variation on a PFR|
Effect of parameter variations on operation of a nonisothermal plug flow reactor
61 minutes ± 36 minutes
Fogler: Chapter 12
This simulation allows the student to explore the effects of various parameters on the performance of a non-isothermal plug flow reactor. The student may choose from eight simulations that span all combinations of exothermic/endothermic reactions and reversible/irreversible reactions, as well as a simulation that takes pressure drop into account. The variable parameters include the heat transfer coefficient, the inlet reactant flowrate, the diluent flowrate, the inlet temperature, and the ambient temperature:
The results of the simulator may be analyzed in the form of plots of
concentration, conversion, or temperature as a function of reactor
The module may also be run in an interactive mode, in which the student
must achieve specific goals (e.g. achieve a given conversion without exceeding
a given temperature within the reactor), in order to get to the center
of the reactor complex.
|Grade Base|| |
In the interactive mode, mastery is based on the correct solution of two consecutive problems (e.g.: arriving at the center of the reactor complex).
We have used the simulator portion of this game as a tool in a group problem solving exercise. Students had to vary various parameters and explain their observations, then use the newly gained insight to optimize a system. A sample assignment, for System 2 in the “individual problems” menu, follows. Since the assignment was to be completed within a one hour class period, explicit instructions and suggestions for parameter values were given.
