Strategies are proposed that promote use of an Integrated Applied Mathematics (IAM) approach to enhance teaching of advanced problem-solving and analysis skills. Three scenarios of 1-dimensional transport processes are presented that support using Error Function analyses when considering short time/small penetration depths in finite geometries.…

As more chemical engineering students enter careers beyond the field, students need more guidance in applying their problem solving skills to a challenges beyond the plant or refinery. Since Fall 2019, we have implemented case-based learning across our Material and Energy Balances course to help students practice chemical engineering thinking as a…

A web database of solved problems has been created to enable faculty to incorporate biological applications into core courses. Over 20% of US ChE departments utilized problems from the website, and 19 faculty attended a workshop to facilitate teaching the modules. Assessment of student learning showed some gains related to biological outcomes, as…

In this article, the author presents five problems that are representative of some of the "movie problems" that he has used on tests in various courses, including reactor design, heat transfer, mass transfer, engineering economics, and fluid mechanics. These problems tend to be open-ended. They can be challenging and can often be worked a variety…

The commercial simulator Aspen Chromatography was employed to study and optimize an important new industrial separation process, weak partitioning chromatography. This case study on antibody purification was implemented in a chromatographic separations course. Parametric simulations were performed to investigate the effect of operating parameters…

The very common situation of waiting for the cooling of a cup of coffee is addressed through a conventional engineering approach, where several important concepts of heat and mass transfer are used. A numerical and analytical solution of the differential equations of the problem are proposed, and assessed by comparing to simple experiments.…

A particle technology design problem incorporating population balance modeling was developed and assigned to senior and first-year graduate students in a Particle Science and Technology course. The problem focused on particle collection, with a pipeline agglomerator, Cyclone, and baghouse comprising the collection system. The problem was developed…

Advances in the biological sciences necessitate the training of chemical engineers to translate these fundamental discoveries into applications that will benefit society. Accordingly, Tulane University revised its core chemical engineering curriculum in 2005 to include a new introductory course in bioengineering and biotechnology for sophomores.…

A hands-on project was developed to educate new chemical engineering students about the types of problems chemical engineers solve and to improve student enthusiasm for studying chemical engineering. In this project, students studied the phenomenon of carbonated beverages going flat. The project was implemented in 2003 and 2004 at Kansas State…

Presents a problem related to mass balances for checking the consistency of measured data from a process. Provides the solution to the problem with diagrams and calculation tables. (YP)

Three mathematics software packages, MathCAD, Point Five, and TK Solver Plus, are described and compared. The packages were rated on the accompanying documentation, ease of learning, ease of use, matrix operations, equation solving capability, versatility, use of units, generation of graphs and tables, readability of output, and overall…

An approach that may be used to introduce the fundamental ideas of thermodynamics using a mathematical background with the knowledge of the behavior of matter is described. The physical background, conservation of energy, predicting the behavior of a system, and solving problems are topics of discussion. (KR)

Various examples of open-ended problems and ways to obtain them are presented. Suggestions for incorporating open-ended problems and some of the benefits and difficulties encountered by teachers and students are discussed. Examples are from courses on mass and energy balances, communications, kinetics and ideal reactors, and reactor design. (KR)

A demonstration used in a heat and material balances class that explains how a reusable heat pack works is described. An initial homework problem or exam question is provided with its solution. A discussion of the solution is included. (KR)

Described is a computer software package suitable for teaching and research in the area of multicomponent vapor-liquid equilibrium. This program, which has a complete database, can accomplish phase-equilibrium calculations using various models and graph the results. (KR)
