NICOP - Development of new Lagrangian computational methods for ice-ship interaction problems (NICE-SHIP)
Abstract
Development of new Lagrangian computational methods for ice-ship interaction problems (NICE-SHIP) This project aims to develop physics-based mathematical models and associated numerical schemes to predict complex flows in multi-phase, multi-species, fluidized media and their interactions with immersed objects which are predominantly solids. Mathematical formulation and their solution of this class of flows is quite difficult because of multiplicity of physics and length and time scales usually involved (e.g. high-frequency disturbances in partially frozen sea with a distribution of ice chunk sizes). Developed computational methodologies will be employed to predict loads on a marine vessel navigating in iced sea environments. A multi-scale analysis approach will be utilized to account for the effect of ice chunks of different sizes and their interaction with the vessel hull. Numerical predictions of measurable quantities (e.g. hull resistance) will be validated against available model test data from external sources. In principle, in the absence of relevant data, a companion experimental project can be initiated elsewhere to generate relevant data. B. The potential development of the Arctic and Antarctic regions warrant analysis tools to 1) develop requirements for new Polar-class vessels, 2) design new vessels, 3) evaluate performance and survivability of current vessels, and 4) help develop operating procedures for ice and non-ice class naval ships. The proposed project aims to provide a stepping stone towards development of such tools. C. Communicated with Dr. Paul Hess and Dr. Ki-Han Kim, both of ONR Code 331. D. The desired outcome of the proposed project is the availability of a numerical scheme and the accompanying solution algorithm to accurately predict both vessel-driven and undisturbed flow field in Arctic/Antarctic ocean environments. This capability will not only augment design of high performance naval vessels in such environments, but also help develop a virtual Arctic/Antarctic ocean environment in which propagation characteristics of acoustic waves can be investigated.
