Development of a Simulation Laboratory for Chemical Engineering Instruction

该项目将证明化学品的可行性 工程模拟实验室（CESL）作为一种工具， 化学工程概念教学。CESL是 旨在灌输一种直观的感觉， 化学加工设备，一个理解， 化学工程师通常只能在几个小时后才能获得 多年的工作经验。模拟可以补充 传统的课堂和实验室体验， 让学生真实地接触过程和现象 太昂贵、太大、太耗时或太危险， 检查其他。 该项目将开发三个"进程"模块。 第一 应表征水箱的排水。 这很简单，但 有趣的问题，将允许集中在一般 模块开发问题。 另外两个模块将是 根据第一次的经验选择，但将是 期望涉及几个处理单元（例如，泵，加热 交换器、反应器）。 其中一个将适用于 稳态运行，另一个处于非稳态 操作。 除了这三个流程模块之外， 该项目将开发一个高级"控制"程序， 管理流程模块的使用方式。 控制 程序将允许模块以三种模式中的任何一种运行 （实验室、稳态或非稳态操作）。 灵活性 控制程序的设计将允许 未来将增加更多模块。 七名教师共同研究人员将密切合作， 工业顾问，学生助理，计算机 供应商和图形编程专家来开发 仿真模块 这些模块将被引入两个 本科课程（秋季单元操作和动力学 在春天）。 将评估以下方面的教学影响： 模块通过平行对照组进行定量比较 指标和离职面谈，以捕捉学生的印象。 已制定计划，传播目前的项目成果 在AIChE和ASEE的年度会议上。 发达 软件和文件将分发给化学 全国各地的工程部门通过一个ftp服务器上 互联网

This project will demonstrate the feasibility of a Chemical Engineering Simulation Laboratory (CESL) as a tool for instruction of chemical engineering concepts. The CESL is designed to instill an intuitive feel for the operation of chemical processing equipment, an understanding that is ordinarily obtained by chemical engineers only after several years of on-the-job experience. Simulation can complement traditional classroom and laboratory experiences by providing the students with realistic exposure to processes and phenomena that are too expensive, large, time-consuming, or dangerous to examine otherwise. This project will develop three "process" modules. The first shall characerize the draining of a tank. This simple, but interesting problem, will allow concentraing on the general problme of module development. The other two modules will be selected buased upon experience with the first but will are expected to involve several process units (e.g., pumpts, heat exchangers, reators). One will be appropriate for use in steaty-state operation, and the other in unsteady-state oepration. In addition to these three process modules, the project will develop a high-level "control" program that governs the way the process modules are used. The control program will allow the modules to be run in any of three modes (Laboratory, Steady, or Unsteady operation). Flexibility in the design of the control program will allow for the incorporation of additional modules in the future. The seven faculty co-investigators will work closely with industrial consultants, student assistants, the computer vendor, and graphics programming experts to develop the simulation modules. The modules will be introduced into two undergraduate courses (Unit Operations in the fall and Kinetics in the spring). Assessment will be made of pedagogic impact of the modules via parallel control groups to compare quantitative metrics and exit interviews to capture student impressions. Plans are in place disseminate the present the project results at annual meetings of the AIChE and ASEE. The developed software and documentation will be distributed to chemical engineering departments across the nation via an ftp server on the Internet.
