It is natural to interpret entropy as a measure of energy dispersion. However, the classical, phenomenological introduction to the topic, which relies on detailed analysis of Carnot engines, obscures this interpretation. Here, we propose a modification of the classical approach, which allows the basic properties of entropy to be proven without…

Contributing to a competency model for engineering thermodynamics, we investigate the empirical competency structure of our exams in an attempt to answer the question: Do we test the competencies we want to convey to our students? We demonstrate that thermodynamic modeling and mathematical solution emerge as significant dimensions of thermodynamic…

The motivation, philosophy, and organization of a course on artificial intelligence in chemical engineering is presented. The purpose is to teach undergraduate and graduate students how to build AI-based models that incorporate a first principles-based understanding of our products, processes, and systems. This is achieved by combining…

In our chemical engineering curricula, students may enroll in introductory thermodynamics as a prerequisite to or as a corequisite with material and energy balances (MEB). We sought to determine why students enrolled in these courses in a given sequence whether it impacts performance. Students' enrollment decisions were mostly based on logistics…

How is it possible to create and continuously improve a quality learning environment for our students? We present our one-year course on engineering thermodynamics as a case study in which we investigate the learning environment based on a competency model from the students' perspective. Based on the analysis of our course structure and exam…

An intensive course in heat transfer was created for the winter break between semesters to provide students with a "second chance" to learn the material and receive a grade of C- or better required to take the subsequent courses in the chemical engineering curriculum. It includes on-line and in-person instruction. Over the three years…

The development, testing, and classroom implementation of a low-cost, reproducible, desktop sized, highly visual double-pipe heat exchanger are presented. Quantitative measurements with the module reveal its usefulness for demonstrating basic and advanced convective heat transfer theory while worksheet-guided inquiries promote student engagement.…

In 2019 and 2020, third-year chemical engineering majors completed a concept inventory at the beginning and end of the semester in their thermodynamics course. Midway through spring semester of 2020, the course switched to emergency remote instruction, replacing hands-on inquiry-based laboratory activities (IBLAs) with short videos. Analysis of…

Although students take courses in transport phenomena and thermodynamics, they probably do not ask whether these two subjects are related. Here we give an answer to that question. Specifically we give relationships between the equations of change for total energy, internal energy, and entropy of transport phenomena and key equations of equilibrium…

Thermodynamics challenges teachers and learners. Its pervasiveness about nature, mathematical abstractness, nonnumerical relations, and complexity in applications can inhibit understanding and usage, especially by undergraduates. Perspectives are given about these obstacles, and some suggestions are made to enhance comprehension of the discipline.

Simulation software has experienced growing interest in chemical engineering curriculums for its usage in commercial engineering practices. This article describes the ASPEN Plus® version 10 (V10) simulations and a student teach students approach to integrate ASPEN in the chemical engineering curriculum at the University of Kansas (KU). Videos,…

This paper describes an undergraduate laboratory experiment where students study the heating behavior of magnetic nanoparticles in the presence of alternating magnetic fields. Average score on the post-test was 45±12% for students who completed the lab online, versus 43±11% for those doing the activity hands-on. Post-test scores were significantly…

More than 40 interactive "Mathematica" simulations were prepared for chemical engineering thermodynamics, screencasts were prepared that explain how to use each simulation, and more than 100 ConcepTests were prepared that utilize the simulations. They are located on www.LearnChemE.com. The purposes of these simulations are to clarify…

We inserted a self-taught molecular modeling project into an otherwise conventional undergraduate chemical-reaction-engineering course. Our objectives were that students should (a) learn with minimal instructor intervention, (b) gain an appreciation for the relationship between molecular structure and, first, macroscopic state functions in…

Flooded heat exchangers are often used in industry to reduce the required heat-transfer area and the size of utility control valves. These units involve a condensing vapor on the hot side that accumulates as a liquid phase in the lower part of the vessel. The heat transfer occurs mostly in the vapor space, but the condensate becomes somewhat…
