Efficient Modeling of Ship Maneuvering in Seaway
Abstract
The objective of this work is to develop an efficient medium-fidelity tool for prediction of maneuvering and seakeeping dynamics of surface ships in waves. The approach is to extend a time-domain, high-order, 3-D boundary element method code, Aegir, initially developed for surface vessels in waves to also simulate the response of the propellers, rudder, and ride control fins simultaneously with the hull in waves. The specific tasks and timeline of this 3-year effort include:~ 9/1/18-8/31/19 (Period 1): Extend & validate Aegir, for hydrodynamic predictions of 3-D hydrofoil performance, where the hydrofoil serves as a canonical proxy to rudders and ride control fins.~ 9/1/19-8/31/20 (Period 2): Extend & validate Aegir for powering predictions in calm waters.~ 9/1/20-8/31/21 (Period 3): Extend & validate Aegir for powering predictions in waves. The proposed research effort will help the US Navy in the development of safe, agile, fuel- efficient, and high-performance platforms by providing an efficient, medium-fidelity tool, Aegir, for prediction of maneuvering and seakeeping dynamics of surface ships in waves. The proposed studies will also help to improve the fundamental understanding of the influence of spatially varying inflow, proximity to free surface, surface waves, and interactions with hull and rudder on the propeller performance.
