Large-Eddy Simulation of Propulsor Crashback
Abstract
We propose to develop the large-eddy simulation (LES) approach to simulate a maneuveringunderwater vessel in propulsor crashback, on unstructured overset grids. The objectives are to (i)develop a novel unstructured overset methodology for LES, (ii) predict the highly unsteady flowaround propulsor in crashback operation and resulting unsteady forces and moments on thepropulsor and the hull, (iii) simulate the 6-DOF effect of hull and appendages, and (iv) developcapability for transient J of a maneuvering underwater vessel. Due to the use of unstructuredoverset grids and LES, the proposed work is in a broader sense developing the computationalcapability to predict a wide range of engineering flows of interest to ONR.
