#1511721 / #1511333 / #1510929 / #1511996Costello, John H. / Dabiri, John, Colin, Sean / Gemmell, BradThe goal of the proposed study is to investigate the mechanisms by which different swimming animals propel and maneuver themselves in order to identify common flow characteristics. 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.

＃1511721 /＃1511333 /＃1510929 /＃1511996Costello，John H. / Dabiri，John，Colin，Colin，Sean / Gemmell，Bradthe Bradthe拟议研究的目标是调查不同的游泳动物和操纵自己以确定常见的常见流动特征的机制。这项工作的结果将适用于可以弯曲和扭曲的车辆的工程，模仿自然界的有效游泳者。自然界中有效的游泳者似乎在弯曲和扭曲的身体时表现出了共同的特征。尽管已经探索了游泳者的其他形态学特征的影响，但这是我们对我们没有良好理解的领域。基本的假设是，各种物种之间的弯曲运动学相似，需要发现这些统一特征。将使用动物信息学测试对广泛动物王国的假设的验证。拟议的工作着重于研究三种不同模型动物（水母，翼足和lamp虫）的推进，因此可以鉴定，表征和理论上分析常见的游泳特征。最先进的实验技术（例如2D和3D粒子图像速度法和全息成像）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定量性的，而且还提供对推进器弯曲的流体动态效应的预测性评估。
