Investigation into the Boundary Layer of an Anguilliform-Like Propulsor

Abstract

The goal of the proposed work is to understand the fluid dynamics of the boundary layer of anundulating propulsor. The research proposed is a numerical and experimental study that willanswer fundamental questions about the physics of the interaction of an oscillating surface withthe surrounding fluid. Commercially available and academic CFD codes will be used to predictthe mechanics of the fluid particles in the oscillating boundary layer. The experimental study willinclude SPIV and LDA measurements of the fluid particles within an oscillating boundary. Themain interest of this study will lead to viscous drag prediction technique that can be used for aunique propulsion concept for ships, boats and submarines.The principal components of the work involve a simple cylinder subjected to pure sway, a simplecylinder subjected to pure yaw, and an undulating anguilliform propulsor (sway and yaw). Bothnumerical and experimental studies will be completed on these scenarios.
