#1511721/#1511333/#1510929/#1511996 Costello，John H./Dabiri，John，Colin，Sean/Gemmell，Brad拟议的研究的目标是调查不同的游泳动物推动和机动自己的机制，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交通工具的工程，模仿大自然中高效的游泳者。在自然界中，高效的游泳运动员似乎在他们的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其他形态特征的影响，但这是一个我们还没有很好了解的领域。基本假设是不同物种之间的弯曲运动学是相似的，这些统一的特征需要被发现。这一假说对更广泛的动物界的验证将使用动物信息学进行测试。这项工作的重点是研究三种不同的模式动物(水母、翼足类和七鳃鳗)的推进能力，以便识别、表征和理论分析常见的游泳特征。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动、力、扭矩和压力场。最终目标是不仅提供推进器弯曲的流体动力效应的定量评估，而且还提供预测评估。

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.
