Bioinspired Submersible Dual Propulsion System: A Novel Approach to Ultra-Efficient Submarine Propulsion Utilizing Starting and Stopping Vortex Rings Mirroring Jellyfish Motion
获奖作品摘要
The goal of hyper-efficient propulsion has already been reached within the animal kingdom as animals such as Jellyfish and Comb Jellies are able to sustain themselves with limited required caloric intake and travel longer relative distances with minimal energy consumption. However, mankind has yet to mimic this process of propulsion to its full effect. Transportation vehicles including ships and submarines have long focused on propulsion efficiency based on traditional methods such as the Froude number that involve high Reynolds Number turbulent flow. The ocean is one of the most difficult frontiers to explore and measure but the need for advancements in ultra-efficient submersible vehicles is becoming critical in order to search and monitor ocean temperatures and chemical composition. The novel dual-prop jet propulsion system presented in this research utilizes both starting and stopping vortices on a rigid platform, inspired by jellyfish propulsion methods, creating a more efficient impulse. In physical models, the results of this research indicate there is up to a 37% improvement in the total impulse and CFD models identify the potential for up to a 75% loss in available passive energy recapture, due to fluid dynamics when comparing the optimal design relative to the control case.

学科简介：工程力学 Engineering Mechanics
Studies that focus on the science and engineering that involve movement or structure. The movement can be by the apparatus or the movement can affect the apparatus.
Subcategories:
Aerospace and Aeronautical Engineering (AER): Studies involving the design of aircraft and space vehicles and the direction of the technical phases of their manufacture and operation.
Civil Engineering (CIV): Studies that involve the planning, designing, construction, and maintenance of structures and public works, such as bridges or dams, roads, water supply, sewer, flood control and, traffic.
Computational Mechanics (COM): A study that applies the discipline and techniques of computer science and mathematics to solve large and complex problems in Engineering Mechanics.
Control Theory (CON): The study of dynamical systems, including controllers, systems, and sensors that are influenced by inputs.
Ground Vehicle Systems (VEH): The design of ground vehicles and the direction of the technical phases of their manufacture and operation.
Industrial Engineering-Processing (IND): Studies of efficient production of industrial goods as affected by elements such as plant and procedural design, the management of materials and energy, and the integration of workers within the overall system. The industrial engineer designs methods, not machinery.
Mechanical Engineering (MEC): Studies that involve the generation and application of heat and mechanical power and the design, production, and use of machines and tools.
Naval Systems (NAV): Studies of the design of ships and the direction of the technical phases of their manufacture and operation.
Other (OTH): Studies that cannot be assigned to one of the above subcategories. If the project involves multiple subcategories, the principal subcategory should be chosen instead of Other.
