摘要
流体机械课程是能源与动力工程专业的核心课程,以流体机械内部流动与性能特征为教学重点,需结合实验有效促进学生对相关理论的理解。空化现象是课程中的教学难点,相关的实验难以实现流动的可视化,且可视化材料在负压条件下易损坏,制约了实验教学的开展。采用开源OpenFOAM软件,构建理论教学、OpenFOAM软件教学以及OpenFOAM软件模拟三位一体的教学模式,以空化实验为案例,模拟空化的变化过程,揭示空化的非稳定特征及其与出口压力的联系。结果表明,新的教学模式弥补了传统实验教学的缺陷,提升了学生的分析与探索能力。
The fluid machinery course is the core course of energy and power engineering majors.It focuses on the internal flow and performance characteristics of fluid machinery.It is necessary for students to effectively understand relevant theories through experiments.Cavitation is a difficult issue in the curriculum,related experiments are difficult to achieve visualization of flow,and visualization materials are prone to damage under negative pressure conditions,which restricts the development of experimental teaching.This article proposes to use the open-source CFD program OpenFOAM to construct a trinity teaching model that integrates theoretical teaching,OpenFOAM teaching,and OpenFOAM simulation.It takes the cavitation experiment as a case and uses the open-source CFD program OpenFOAM to simulate the development of cavitation,revealing the unstable characteristics of cavitation and its relationship with outlet pressure.The results indicate that the new teaching model compensates for the shortcomings of traditional experimental teaching and enhances students'analytical and exploratory abilities.
