The Eco-Hydrodynamics Group (Eco-Hydro Group), led by Yuncheng Xu from China Agricultural University, currently focuses on scientific and engineering issues related to the coupling of biological (animal/plant) habits and hydrodynamic environments in the research fields of hydraulic engineering, agricultural engineering, environmental engineering, etc. Specific issues include but are not limited to: field applications of quadruped robots, research on hydrodynamic characteristics of complex pipe networks, research on mussel self-organization behavior based on hydrodynamics, research on intelligent collaborative control technology for variable irrigation of large-scale sprinklers, biological fouling in water transfer projects, and so forth.

We comprehensively employ multi-scale theoretical modeling approaches, integrating with the OpenFOAM open-source computational fluid dynamics (CFD) platform, ROS2 robotic operating system, Python numerical analysis tools, etc. By constructing multi-physics coupling models, it systematically analyzes the material transport and momentum transfer mechanisms in the interaction process between biology and hydrodynamic environment. Relying on a multi-dimensional research system combining high-precision indoor flume experiments, in-situ field monitoring, and numerical simulation validation, the group deeply integrates interdisciplinary theories such as biological ethology and agricultural engineering. Aiming at key scientific issues in hydraulic engineering, agricultural engineering, and environmental engineering, it carries out full-chain research from microscopic biological fluid mechanics phenomenon observation to macro-engineering application, committed to revealing the dynamic nature of the coupling between biology and water environment, and providing theoretical support and technical solutions for the optimal design of water transfer systems, intelligent irrigation technology innovation, river ecological restoration projects, and bionic robot research and development.
