摘　　要：随着科学技术的发展,逆向工程被广泛运用于工业设计中。逆向工程技术具有有效缩短产品设计、开发周期,降低新产品开发成本的优点。本文以一专用于大变幅水头条件下的混流式水轮机转轮为研究对象,探索研究混流转轮逆向建模过程中的重点与难点,最后通过水轮机全流道数值模拟验证了转轮逆向结果的可靠性,为混流式水轮机逆向工程持续深入的研究工作提供参考。With the development of science and technology,reverse engineering is widely used in industrial design.Reverse engineering technology has the advantages of effectively shortening product design and development cycle and reducing the development cost of new product.In this paper,a Francis turbine runner specially designed for the operating condition of large variable water head is taken as the research object,and the key points and difficulties in the reverse modeling process of the Francis runner are explored and studied.Finally,the reliability of the research result is verified by numerical simulation of the turbine with full flow passage,which provides a reference for the continuous and in-depth research of reverse engineering of the Francis turbine.
