伯努利方程教学实验与数值仿真应用
|
摘要
实际物理实验与计算机技术应用紧密结合是力学实验教学模式改革和创新发展的趋势,对实验的计算机数值仿真是不同于计算机虚拟仿真的另一种实验教学辅助方法。以圆管稳定粘性总流伯努利方程教学实验为研究对象,较全面地说明了实验及归纳和分析实验测量数据及其变化规律。应用FLUENT流体软件,对实验的实际粘性流场进行计算机数值仿真分析。通过实际实验和计算机数值仿真相结合,从总水流测量到流场分布全面分析流动数据,使学生能够更加牢固掌握实验原理和深入理解有关概念,增强创新实践能力。
The close combination of physical experiment with computer technology application is thetrend of reform and innovation development in mechanics experiment teaching, the numerical simula-tion of the experiment is another assist method of experiment teaching different from the computer virtu-al simulation. Based on Bernoulli equation teaching experiment of steady total viscos flow in the circulartubes, a comprehensive summary and analysis of the experimental measurement data and it.s variationlaws was carried. The FLUENT software was used for computer numerical simulation of viscous flowfield of the actual experiment. The actual experiment combined with computer numerical simulation cananalyze data from the total water flow to flow field distribution, guiding and helping students to graspfirmly experiment principle and understand deeply relevant important concepts, and enhancing practi-cal innovation ability.
