在线算法演示虚拟仿真平台开发——以热传导为例

为缩短传统算法演示流程，降低学习成本，开发基于Web的应用程序，建立无须安装插件或额外运行时的轻量级虚拟仿真平台，在浏览器中开展热传导虚拟实验教学。仿真平台基于开源库Vue-repl、Element plus、MathJax和ECharts构建，可展示高可交互的用户界面，计算结果可视化呈现。为形象直观理解数值仿真过程及算法实现，学生可在浏览器中编辑源代码，修改物性参数、空间步长与时间步长、残差控制等计算参数，将仿真结果通过图表展示。实验仿真平台基于开源软件构建，简化了传统热传导仿真流程。     

基于 WebGL 的换热器三维 Web 应用设计与开发

Web application in industrial engineering design process has been discussed with the aim to improve the calculation speed involved,avoid errors in manual calculation,improve reusability,and realize 3D real-time preview of design. Taking the design of heat exchanger for air conditioning and refrigeration as an example,this paper introduces the Web application and WebGL in industrial engineering design,including pre-processing,calculating and post-processing. In the post-processing,the 3D preview of refrigeration design has been realized based on WebGL. The drawing sheet for the heat exchanger have been completed through Web application. The practice shows that the Web application can effectively reduce the manual calculation workload in the design process of heat exchanger,also reduce the manual calculation workload in the trial calculation. And two-dimensional or three-dimensional drawing sheets could be directly generated via the Web application,so as to avoid the calculation error via manual calculation,and to avoid the modification of drawing sheets manually when working conditions are changed.
