Learning Outcomes

After completing Class 37 you should…

  • Know the definition/defining equation for dispersion coefficient
  • Understand
    • under most circumstances, predictions using the axial dispersion model are negligibly different from predictions using the ideal PFR model
    • when the dispersion coefficients are treated as fitting parameters, the axial dispersion model can be used to model reactors that are neither ideal PFRs nor CSTRs
    • when the dispersion coefficients are very large, the axial dispersion model predictions approach those of the ideal CSTR model
    • when the dispersion coefficients are very small, the axial dispersion model predictions approach those of the ideal PFR model
  • Be able to
    • calculate the output molar flow rates and temperature from a given reactor using an axial dispersion reactor model
