Tinker With and Think About Transport Phenomena-Using Experiments and Dimensionless Groups to Understand Nonlinear Interactions Via a "Proof of Concept Proposal"

该项目正在开发实践实验和解释材料，训练学生根据运输和流体动力学不稳定性的思想分析运输现象中的多个长度和时间尺度。实验主要包括简单的桌面演示，具有灵活性和可变性。该材料以WEBCT格式提供，使用图片论证、比例论证和数学分析解释实验现象，并通过动画和工程、日常经验和自然现象的应用予以加强。每个实验和附带的材料都是独立的，可以以模块或模块组的形式导出到热量，质量和动量传输的课程中。这些实验和视频剪辑正在构建中，以便它们可以用于化学，机械，材料和生物医学工程以及工程物理课程。拟议原型的受益者是本科生和教师。实验是特别有帮助的视觉直观的学生，其欣赏不在于数学模型，而在艺术形式和物理现象的基础。然而，它们也有利于分析演绎型学生，并激发这两种类型学生的创造力。教授受益是因为动手实验有望使讲座活跃起来，并保持学生的兴趣。原型正在课堂环境中进行测试，并在项目的形成和执行阶段进行评估。建议的智力价值：建议的活动是基于PI二十多年的研究经验。学生们正在学习创造性地思考，并将运输现象视为一个可以容忍的数学问题。其智力价值在于，受影响的受众实际上学会了成为知识分子，而不是数字处理技术人员。建议的更广泛影响：建议的研究鼓励本科生和研究生参与编写教育材料。因此，鼓励学生参与教育过程，并将教学和研究视为一种职业。在这个概念验证阶段，该项目的成果正在佛罗里达大学试用。PI还将材料发送到爱达荷州大学，他们的一名教师正在尝试在流体流动和传输课程中使用这些材料。这两所大学都有大量的妇女和少数民族学生。通过电子媒体和主要会议进行传播。

This project is developing hands-on experiments and explanatory material that train students in analyzing multiple length and time scales in transport phenomena based on ideas of transport and hydrodynamic instabilities. The experiments mostly comprise of simple tabletop demonstrations and have both flexibility and variability. The material is being made available in a WEBCT format and explains experimental phenomena using picture arguments, scaling arguments and mathematical analysis and is fortified with animations and applications to engineering, everyday experience and natural phenomena. Each experiment and accompanying material is a stand-alone and can be exported in modules or in groups of modules to classes in heat, mass and momentum transport. These experiments and video clips are being constructed so that they are of use to curricula in chemical, mechanical, materials, and biomedical engineering, and engineering physics.The beneficiaries of the proposed prototype are undergraduate students and faculty alike. The experiments are particularly helpful for the visual intuitive student whose appreciation does not lie in the mathematical model, rather in the art form and in the physics underlying the phenomena. Yet, they also benefits the analytical deductive student and stir up creativity in both types of students. The professor gains because the hands-on experiments are expected to liven up the lectures and sustain the interest of the student. The prototypes are being be tested in a classroom setting and evaluations are being conducted both during the formative and execution phases of the project.Intellectual Merit of the Proposal: The proposed activity is based on over twenty years of research experience of the PI. The students are learning to think creatively and view transport phenomena as more than a mathematical subject to be tolerated. The intellectual merit lies in the fact that the affected audience actually learns to become intellectuals instead of number-crunching technicians.Broader Impacts of the Proposal: The proposed study encourages the participation of undergraduate students and graduate students in the development of the educational materials. As a result, students are being encouraged to participate in the education process and consider teaching and research as a career. In this Proof of Concept phase, the results of the project are being tried at the University of Florida. The PI is also sending materials to the University of Idaho where one of their faculty members is trying the materials in a course on fluid flow and transport. Both universities have substantial numbers of women and minority students. Dissemination is via the electronic media and major conferences.
