基于Matlab GUI的渗流力学虚拟仿真实验平台开发
|
摘要
为了改变渗流力学实验内容单一的教学现状,进一步推广渗流力学的可视化教学,基于Matlab2015a平台,使用有限元方法,分别对不同求解域和边界条件下的稳态和非稳态渗流数学模型进行求解,开发了各种渗流力学虚拟仿真实验平台。该虚拟仿真实验平台分为:单井、双井、井网和复杂井4个渗流模块,学生可以通过图形用户界面,与内部的Matlab代码进行人机交互,对不同渗流模型下的渗流场进行数值模拟,从而完成渗流力学虚拟仿真实验。相对于传统的渗流力学教学实验——水电模拟实验,虚拟仿真实验平台具有内容丰富多彩、可视化效果好、造价低廉、节约实验耗材、低碳环保、课时安排灵活等优点,应用于渗流力学教学过程中,有助于学生理解复杂的渗流过程和渗流机理,加深对流体渗流的感性认识,进而提高课堂效率,具有较高的实用性和较广的推广前景。
To improve the currently poor situation of Flow in Porous Media experiment teaching,the visualization teaching of Flow in Porous Media is further promoted. Based on MATLAB 2015 a platform,the finite element method is firstly implemented to solve the mathematical models of both steady flow and unsteady flow in porous media in different domains and under various boundary conditions by using MATLAB GUI programming to recall the finite element functions built in MATLAB PDE toolbox. Further,an integrated simulation experiment platform is developed,which contains various flow models in porous media. The virtual simulation experiment platform is divided into four modules:single well module,double well module,well pattern module and complex well module. Students can interact with internal MATLAB code through graphical user interface,conduct the numerical simulations of the flow fields under different conditions and then complete the virtual simulation experiment of Flow in Porous Media. Compared with the conventional hydroelectric simulation experiment,the virtual simulation experiment platform has the advantages of abundant models, colorful visualized effects, low cost, consumptive material saving, low carbon, environment protection,flexible teaching schedule and so on. When it is applied to Flow in Porous Media teaching,the platform will help students to understand the complex flow process and flow mechanism,deepen their perceptual impression of fluid flow in porous media,and improve the efficiency of classroom. Therefore,the platform has high flexibility and wide application prospects.
