研究问题 Scope

生态水动力学课题组（Eco-Hydro Group）是由中国农业大学徐云成负责，目前主要关注水利工程、农业工程、环境工程等研究领域中的生物（动物/植物）习性-水动力环境耦合相关的科学问题和工程问题，具体问题包括但不限于：复杂管网水动力学特性研究、基于水动力学的贻贝自组织行为研究、大型喷灌机变量灌溉智能协同控制技术研究、变量灌溉专用水力控制阀、输调水工程生物污损、微灌系统灌水器堵塞等。

主要使用理论建模和基于OpenFOAM的数值计算方法，辅以室内试验和野外现场观测的手段，与生态行为学、农业工程等方面的研究者合作，在复杂自然条件或人造工程中，探索动物、植物、微生物与水环境发生的物质交换、动量传递等过程，揭示其中的水动力学机理，对生物的生理结构奥秘和运动行为规律做出解释，为输调水系统、灌溉系统、河道生态修复等工程设计以及仿生机械设计提供理论依据和技术指导。

The Eco-Hydrodynamics Group (Eco-Hydro Group) is led by Dr. Yuncheng Xu at China Agricultural University (CAU). We mainly focus on the scientific questions and engineering problems related to the coupling between biological (animal/plant) habits and the hydrodynamic environment, in the research fields of hydraulic engineering, agricultural engineering, environmental engineering, and so forth. The specific questions may include but not limit to bio-fouling in water-transfer projects, emitter clogging in micro-irrigation systems, canopy interception in spraying irrigation, plant growth modeling affected by irrigation, and so forth.

We utilize theoretical modeling and numerical simulation based on OpenFOAM, supplemented by experimental methods, to explore the processes such as mass transfer and momentum transport between animals, plants, microorganisms and the aquatic environment, in the complex natural conditions and man-made structures, in the cooperation with researchers in ecological Behaviors and agricultural engineering. We want to explain the mysteries of biological structures and locomotion behaviors, by revealing the hydrodynamics mechanisms involved. Ultimately, our studies will provide theoretical and technical guides for the engineering designs such as water-transfer systems, irrigation systems, stream restoration, and bionic mechanical designs.
