Significance of Mixing in Chemical Reactor Design

Jorge Gatica, Cleveland State University, Chemical and Biomedical Engineering
Author Profile


This activity review fundamentals of chemical reactor design, and examines the effects of mixing models on reactor performance.

Learning Goals

Interaction with data files
Solution of the Design Equations
(algebraic, integral, and differential equations)
Numerical integration
Graphical Analysis

Context for Use

The activity is a higher-level learning exercise completed in class, as a class exercise complemented by group activities. Students are expected to have already completed an introductory MATLAB class (typically a freshman-level class at my institution, Calculus II and Differential Equations; freshman and sophomore MTH classes). It is geared for all Engineering disciplines. Chemical, Biomedical, Mechanical, and Environmental Engineering majors will see direct applications)

Description and Teaching Materials

Students are presented with two scenarios illustrating typical residence time distribution exercises. The activity illustrates how to predict the performance of a chemical reactor using ideal flow models, and comparing against two mixing models.

Teaching Notes and Tips

N/A, see files uploaded


Students are assigned several home problems that need to be solved using these tools. Group activities during class exercises are also submitted for assessment and feedback.
