How Do Animals Harness Water

项目摘要

In this project the PI will synergistically integrate biological and state of the art quantitative experiments along with mathematical modeling to investigate the interfacial dynamics of coupled water entry and exit problems as manifested in animal systems. This work will focus on biological behaviors that include both water exit and entry, in particular focusing on locomotion on the water surface and animal drinking. This offers a unique underlying opportunity: to learn how nature uses the interaction of these forces and thereby develop the knowledge that will enable novel bioengineering and bio-inspired systems. The PI's approach will use mathematics, biology and engineering to investigate the hydrodynamic principles that underlie and enable specific animal water entry and exit behaviors, as well as to develop mathematical models for such complex dynamics. The PI will identify how differences in animal movement patterns, body size, and surface characteristics relate to differences in performance in fluid transport (drinking) and fluid force generation (locomotion across or through interfaces). In the modeling of interfacial dynamics, the PI will develop water exit models and also modify the current theory to integrate water entry followed by exit, as suggested by relevant aspects of animal movements. In physical experiments, the effort will quantify processes of water entry and exit with various well-controlled parameters. This approach provides a complete framework that has not been implemented in these systems before. This project will provide interdisciplinary training for graduate and undergraduate students by training them in fluid mechanics, biomechanics and biology as well as in experimental methods combined with rigorous mathematical modeling.

在该项目中，PI将协同整合艺术定量实验的生物学和状态以及数学建模，以研究耦合水进入的界面动力学，并退出动物系统中表现出的问题。这项工作将重点放在包括水出口和进入的生物学行为上，特别是集中于水面和动物饮酒的运动。这提供了一个独特的基本机会：了解自然如何利用这些力的相互作用，从而发展知识，从而使新颖的生物工程和生物启发的系统。 PI的方法将使用数学，生物学和工程学来研究基于并实现特定动物水进入和退出行为的流体动力学原理，并为这种复杂动力学开发数学模型。 PI将确定动物运动模式，体型和表面特征的差异与流体传输（饮酒）和流体力产生（跨接口或通过接口的运动）的性能差异有关。在界面动力学的建模中，PI将开发出水出口模型，并修改当前的理论，以整合水进入，然后出口，如动物运动的相关方面所暗示。在物理实验中，这项工作将用各种良好控制的参数量化进入水的过程和退出过程。这种方法提供了一个完整的框架，以前在这些系统中尚未实现。该项目将通过培训流体力学，生物力学和生物学以及实验方法与严格的数学建模相结合，为研究生和本科生提供跨学科培训。
