CBET -0854542 Mohseni, Kamran This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This research program addresses the fundamental science of jet and vortex propulsion by Cephalopods (squid, cuttlefish, etc) and Medusa (Jellyfish) in contrast to more well-investigated aquatic locomotion through body and fin undulations like most fish. We plan a hybrid experimental, computational, and theoretical approach to understand and advance hydrodynamics and biomimicry of aquatic jet propulsion. The research plan has three main thrusts Kinematic Investigation, Computational Fluid Dynamics (CFD) and Experimentation and Biomimicry. A squid care and storage facility will be built for investigation on aquatic thrust-generation mechanism by jet and vortex flow. High-speed photography and flow visualization will provide kinematic data for the squid mantle cavity and siphon during several flow regimes including escape and maneuver. These new simultaneous and detailed measurements are needed for direct numerical simulation of squid locomotion based on the measured kinematic data. In addition, the swimming performances such as swimming velocity, thrust, power requirement and efficiency can be computed directly. The knowledge gained in the kinematic and CFD studies will be translated into engineering design and testing of bio-inspired actuators for effective underwater propulsion. The actuators will be modeled and experimentally characterized. Design of reliable underwater vehicles for sensor networking is playing a major role in National and Homeland Security and costal area protection. Efficient Autonomous Underwater Vehicles (AUVs) are needed for long-term operation in oceans for coastal area monitoring and protection and data collection related to global warming. This project provides an application focus that will be of interest to researchers and students working in ocean engineering, vehicle systems, and biologists. Undergraduate research assistants will be sought via supplementary REU support. The PI intends to develop a course on bio-propulsion while existing disciplinary courses will be enriched with this work, expanding student multidisciplinary exposure. A summer Bio-propulsion Summer Camp for local secondary school students to participate in a week-long educational activity and an International Exchange Student Program, initiated by the PI, will be expanded.

CBET -0854542 MOHSENI，KAMRAN，该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。这项研究计划涉及Jet和Vortex推进的基本科学，该科学是通过cephalopods（squid，cicid，cutther，etcterfiend of Medus and Medus and Medus and fine finef）在相反的情况下（squid and Fination of Figation of Figation）大多数鱼。我们计划一种混合实验，计算和理论方法，以理解和推进水生喷射推进的流体动力和仿生。研究计划具有三个主要推力运动学研究，计算流体动力学（CFD）以及实验和仿生。将建立鱿鱼护理和储存设施，以调查喷气和涡流流的水生推力生成机制。高速摄影和流动可视化将为包括Escape和Aneuver在内的几个流程度提供鱿鱼地幔腔和虹吸管的运动学数据。这些新的同时且详细的测量是基于测量的运动学数据直接对鱿鱼运动的直接数值模拟。此外，可以直接计算游泳速度，推力，功率需求和效率等游泳表演。 在运动学和CFD研究中获得的知识将转化为生物启发的执行器的工程设计和测试，以进行有效的水下推进。执行器将进行建模并实验表征。可靠的水下车辆用于传感器网络的设计在国家和国土安全和沿海地区保护中发挥了重要作用。在沿海地区监测，保护以及数据收集与全球变暖有关的海洋中，需要有效的自动驾驶水下车辆（AUV）。该项目提供了一种应用重点，这将引起海洋工程，车辆系统和生物学家的研究人员和学生的关注。将通过补充REU支持寻求本科研究助理。 PI打算在现有的纪律课程中开发一门关于生物推广课程的课程，以扩大学生的多学科接触。一个夏季生物苏格拉夏季夏令营，供当地中学生参加为期一周的教育活动，并将扩大由PI发起的国际交流学生计划。
