Interactive Mathematica Simulations for Chemical EngineeringMore than 65 interactive Mathematica simulations have been prepared for four chemicalengineering courses: kinetics/reactor design, thermodynamics, fluid mechanics, and heattransfer. They were prepared using the Mathematica programming language and are availableon the Wolfram Demonstration Project website(http://demonstrations.wolfram.com/search.html?query=Chemical%20engineering). They canbe used without a Mathematica license. They use the Manipulate command in Mathematica tocreate on-screen controls that allow users to change system variables. One of the key featuresof these simulations is that the calculations are done in real-time as input parameters aremanipulated using user-friendly controls, and the graphical output appears almostinstantaneously. Interactive simulations have been used extensively in physics education, andstudent interaction with computer simulations is known to have positive effects on learning andpromote student inquiry and exploration.These simulations have been used in class after asking students to predict system behavior aspart of a ConcepTest with student-held clickers. They have also been used outside of class aspart of assignments and in office hours to help students understand important concepts. Theyare excellent for demonstrating the idea of parametric sensitivity. A number of theseinteractive simulations have been used as part of screencasts prepared for information deliveryoutside of class (flipped classroom), and these screencasts are posted onwww.LearnChemE.com. Some of the simulations are being used to prepare interactive tutorialsfor students to use on their own. In the first of these tutorials, which are on phase equilibrium,the concepts are introduced using simplified versions of the simulations that only allow onevariable to be manipulated so that the tutorial contains a number of simulations.
