虚拟仿真在工程热力学课程教学中的应用

Application of virtual simulation in engineering thermodynamics teaching

燃气轮机装置热力循环是工程热力学课程中的重要知识点。为加深学生对相关概念的理解,弥补传统工程热力学实验在热力循环章节内容方面的空白,依托航空发动机虚拟仿真平台开设了航空发动机热力循环分析实验。通过虚拟试车和实验数据分析加强学生对相关知识点的理解,提升学习效果。教学实践表明,该实验有效地解决了燃气轮机装置热力循环知识点比较抽象的问题,帮助学生将相关理论知识与实际工程相结合,提升了学生的创新实践能力,为飞行器动力工程专业后续专业课程的学习奠定了良好的基础。

Thermodynamic cycle of gas turbine engine is an important knowledge point in the course of engineering thermodynamics.In order to deepen students’understanding of relevant concepts and make up for the gap in thermal cycle content of traditional engineering thermodynamic experiment,aeroengine thermal cycle analysis experiment is set up based on Aeroengine virtual simulation test bench.Students’understanding of relevant knowledge points is strengthened and learning effect is improved,through virtual test run and experimental data analysis.Results show that the experiment effectively solves the problem of abstract knowledge points of thermal cycle of gas turbine device,helps students get acquainted with relevant theoretical knowledge and practical engineering,improves students’innovative practice ability,and lays a good foundation for the follow-up professional courses of flight vehicle power engineering.
