Abstract

Hands-on experience in the laboratory is essential in chemical engineering education to enhance the understanding of abstract theories and their effect on chemical processes. In this work, we describe a laboratory class, which combines some of the main engineering concepts into a set of hands-on experiments and simulations. Students are introduced to an iodine clock reaction performed in multiple different reactor types and are instructed to determine the reaction kinetics. Subsequent analysis of the experimental data in Python teaches basic programming skills and the concepts of numeric integration and optimization. Finally, a digital twin of one of the reactors is developed in COMSOL Multiphysics to give the students an application-focused introduction to more-dimensional multiphysics modeling. The students thereby get practical insights into the different methods and stages of reactor and reaction engineering. Based on the students’ assignments, we consistently see a deeper understanding of reaction kinetics and reactor engineering than in the accompanying traditional lecture.

化学过程工程学生动手动力学测量和模拟
在化学工程教育中,为了提高对抽象理论及其对化学过程的影响的理解,在实验室的实践经验是必不可少的。在这项工作中,我们描述了一个实验课,它将一些主要的工程概念结合到一组动手实验和模拟中。向学生介绍在多种不同类型的反应器中进行的碘时钟反应,并指导他们确定反应动力学。随后用Python对实验数据进行分析,教授基本的编程技能以及数值积分和优化的概念。最后,在COMSOL Multiphysics中开发了其中一个反应器的数字孪生,为学生提供了以应用为重点的多维多物理场建模介绍。因此,学生们对反应堆和反应工程的不同方法和阶段有了实际的了解。根据学生们的作业,我们一致看到他们对反应动力学和反应器工程的理解比传统讲座更深入。

期刊介绍: Education for Chemical Engineers was launched in 2006 with a remit to publisheducation research papers, resource reviews and teaching and learning notes. ECE is targeted at chemical engineering academics and educators, discussing the ongoingchanges and development in chemical engineering education. This international title publishes papers from around the world, creating a global network of chemical engineering academics. Papers demonstrating how educational research results can be applied to chemical engineering education are particularly welcome, as are the accounts of research work that brings new perspectives to established principles, highlighting unsolved problems or indicating direction for future research relevant to chemical engineering education. Core topic areas: -Assessment- Accreditation- Curriculum development and transformation- Design- Diversity- Distance education-- E-learning Entrepreneurship programs- Industry-academic linkages- Benchmarking- Lifelong learning- Multidisciplinary programs- Outreach from kindergarten to high school programs- Student recruitment and retention and transition programs- New technology- Problem-based learning- Social responsibility and professionalism- Teamwork- Web-based learning
