UNS: Collaborative Research: Fluid mechanical basis of universal natural propulsor bending patterns

科斯特洛，约翰·H. /达比里，约翰，科林，肖恩/格默尔，布拉德这项拟议研究的目标是调查不同游泳动物推动和操纵自己的机制，以确定共同的流动特征。这项工作的结果将适用于可以弯曲和扭曲的车辆工程，模仿自然界的高效游泳者。自然界中高效的游泳者似乎在身体弯曲和扭曲方面表现出共同的特征。虽然已经探索了游泳者的其他形态特征的影响，但这是一个我们没有很好理解的领域。其基本假设是不同物种之间的弯曲运动是相似的，这些统一的特征需要被发现。该假设在更广泛的动物王国的验证将使用动物信息学进行测试。本文拟对三种不同模式动物（水母、翼足类和七鳃鳗）的推进力进行研究，从而识别、表征和理论分析共同的游泳特征。最先进的实验技术（如2D和3D粒子图像测速和全息成像）将用于量化这些动物模型在弯曲过程中产生的流量，力，扭矩和压力场。最终目标是提供推进器弯曲流体动力效应的定量和预测评估。

Results of this work will be applicable to the engineering of vehicles that can bend and twist, mimicking efficient swimmers from nature.Efficient swimmers in nature appear to exhibit common traits in the bending and twisting of their bodies. While the effects of other morphological characteristics of swimmers have been explored, this is an area that we do not have a good understanding. The basic hypothesis is that the bending kinematics among various species are similar, and these unifying characteristics need to be discovered. Validation of the hypothesis to the broader animal kingdom will be tested using animal informatics. The proposed work focuses on the study of the propulsion of three different model animals (jellyfish, pteropods and lamprey), so that the common swimming traits can be identified, characterized and theoretically analyzed. State-of-the-art experimental techniques (such as 2D and 3D particle image velocimetry and holographing imaging) will be used to quantify the flow, the forces, the torque and the pressure fields generated during bending by these animal models. The final goal is to provide not only quantitative but also predictive evaluation of the fluid dynamic effects of propulsor bending.
