Abstract: Based on the demand for cultivating "compound outstanding engineering talents" under the new Engineering paradigm, combining the characteristics of fluid mechanics experimental teaching, a four-dimensional integration mode comprising ideology and politics integration, teaching methods integration, scientific research and competition integration, as well as real problem integration has been adopted to conduct experimental teaching. The practice shows that under this teaching model, students' practical innovation abilities have significantly improved, demonstrating outstanding performance in various competitions. This mode realizes the transformation of experimental teaching from "verification" to "exploration", and from "knowledge inheritance" to "ability cultivation", providing valuable experience for experimental teaching reforms.
