本科流体力学课程中引入CFD内容的探索与实践

Exploration and practice of fluid mechanics course adding computational fluid dynamics for undergraduates

流体力学是大部分工科学生的专业基础必修课,计算流体力学软件是流体力学科学与工程研究的重要工具。首先,论证流体力学教学中适当引入计算流体力学的必要性;其次,从理论基础、教学条件、学时安排、教学内容、学时分配和考核办法等方面论证了在流体力学教学中适当引入计算流体力学的可行性;最后,为了激发学生的学习积极性和主动性,提升教学质量,尝试性地在教学中引入了计算流体力学。结果表明,引入计算流体力学后能激发学生对流体力学的兴趣,提高学生的学习能力,培养学生的创新性思维,拓宽学生的知识面,加深学生对基本理论的理解,从而提高教学质量,学生期末成绩明显提高。文章提出的流体力学课程改革新思路,为今后引入计算流体力学教学提供了必要的准备和参考。

Fluid mechanics is a major course of the most students in engineering specialty. Computational fluid dynamics software is an important tool in the study of fluid mechanics science and engineering. Firstly, the necessity of adding the contents of computational dynamics to undergraduate learning is discussed. Secondly, the feasibility of adding the contents of computational dynamics to undergraduate learning is discussed in the theoretical basis, teaching conditions, class hours, teaching content and class hour allocation and assessment methods. Finally, the preliminary attempt has carried in the teaching process in order to stimulate students’ learning enthusiasm and initiative, to improve the quality of teaching. The results show that the students’ interest was stimulated, the understanding of basic theory was deepened and the teaching effect was improved after adding the contents of computational fluid dynamics to undergraduate learning. Compared with the past, the students’ final average score has improved. The new ways of teaching reform about this curriculum are put forward in this paper on the basis of in-depth research and analysis of the main problems existing in the teaching practice.
