DEVELOPMENT OF A METHODOLOGY TO VISUALIZE AND CONDUCT A PHYSICAL EXPERIMENT AS A WEB-BASED VIRTUAL EXPERIMENT

摘要

A methodology is developed and described to convert a physical experiment from the undergraduate thermo-fluids engineering laboratory into a web-based virtual experiment. Several important characteristics of the physical experiment are identified so that they can be preserved in a physical to virtual domain mapping of the experiment. Six unique aspects that will eventually be included in web-based virtual experiments are: the use of computer generated (virtual) data for recreating physical phenomenon; virtual measurement on a computer screen; virtual assembly for positioning virtual probes prior to commencement of the experiment; coupling of the virtual experiment with data acquisition software; real time collaboration in the virtual domain and virtual reality laboratory environment. The present work combines three of these aspects simultaneously: use of simulated data for recreation of physical phenomenon, virtual measurement, and data acquisition and analysis. A modular structure with three district sub-modules is proposed for the web-based virtual experiment currently being developed. The web-based module is currently intended for use by students as a practice tool before they conduct the physical experiment is the thermo-fluids laboratory course. It is also expected to impact the development of virtual engineering laboratories for web-based distance learning undergraduate programs.
