An Inverted Classroom Approach to Educate MATLAB in Chemical Process Control
Publication date: Available online 12 October 2016 Source:Education for Chemical Engineers Author(s): Xianhua Li, Zuyi (Jacky) Huang The inverted-classroom teaching format and the application of MATLAB/Simulink have recently generated considerable research interest in chemical engineering education. MATLAB/Simulink was introduced in mathematics-intensive courses due to its user- friendly interface for mathematical model simulations. Inverted classroom approach has been reported to be generally beneficial for engineering courses, but it has never been applied to MATLAB/Simulink education in a single course. The aim of o...

Team-based Learning for First Year Engineering Students
Publication date: Available online 17 September 2016 Source:Education for Chemical Engineers Author(s): Vesna Najdanovic-Visak Although it was originally developed for a business school environment to promote the benefits of small-group teaching in a large group setting, the method of the Team-based Learning (TBL) has recently been increasingly used within medical education. On the other hand, the reports on its implementation in engineering and science education are much scarcer. The aim of this work is to discuss the experience, evaluation and lessons learned from the implementation of the TBL within a Year 1 engineer...

Implementation of a Block-Oriented Model Library for Undergraduate Process Control courses in EMSO Simulator
Publication date: Available online 15 September 2016 Source:Education for Chemical Engineers Author(s): J. Ospino, M.E. Sánchez, A.R. Secchi Process control courses usually have a section of the course focused on the building of block diagrams for modeling, simulation, and analysis of open and closed loop processes. For this purpose, students are often oriented to build models using SIMULINK or XCOS because of the versatility of these powerful tools in the easy construction of mathematical models using the concept of block-oriented programming. In this paper we propose a model library built in the software EMSO that ...

Teaching process simulation using video-enhanced and discovery/inquiry-based learning: Methodology and analysis within a theoretical framework for skill acquisition
Publication date: Available online 15 September 2016 Source:Education for Chemical Engineers Author(s): Daniel J. Belton Process simulation has become an essential tool for chemical engineers in education and industry. Various studies examining the teaching and learning of process simulation are available, although no clear theoretical frameworks for process simulation pedagogy currently exist. The work presented here describes a methodology for teaching process simulation that utilises video-enhanced and exploratory-based learning. The teaching approach is evaluated for a cohort of first year students, with the evaluat...

The teaching of enhanced distillation processes using a commercial simulator and a project-based learning approach
Publication date: Available online 13 September 2016 Source:Education for Chemical Engineers Author(s): Lourdes Calvo, Cristina Prieto When a multicomponent fluid mixture is non-ideal, its separation is difficult; thus, enhanced separation processes with several equipments are required. Commercial chemical processes simulators must be used to design these difficult separations, so ChE students have to learn them. This work shows the teaching methodology and outcomes of using computer labs with Aspen Plus to solve advanced distillation processes within a fourth year course of the ChE degree. Lectures on theoretical aspe...

Creating shared resources for pharmaceutical technology education —Simulation tools
This article describes the use of the HUBZero middleware to create shared simulations of particulate processes in drug product manufacturing. These simulations are deployed on the pharmaHUB.org Web-site and are accessible through a Web-browser. The simulations may be used to introduce basic concepts in solids processing and their application to drug product design and process development. Graphical interfaces that allow students to visualize the models being studied may be constructed with the Rappture toolkit. This toolkit generates an interface from a simple input/output description that is applicable to many simple but ...

Publication date: July 2014 Source:Education for Chemical Engineers, Volume 9, Issue 3 Author(s): C.D. Luzi, S.P. Bressa, G.D. Mazza, G.F. Barreto In spite of the widespread industrial application of non-catalytic or homogeneously catalyzed gas–liquid reactions (GLRs), many undergraduate chemical engineering curricula do not include this subject and heterogeneous catalysis provides the only example of a heterogeneous chemical reaction system. Textbooks dealing with GLRs describe and formulate separately the different processes affecting the rate of chemical absorption, without providing a clear picture of the...
