Abstract
DEVELOPMENT OF FAR WAKE SOLVER FOR SHIP TRANSIENT MANEUVERS IN WAVES, AND SUPPORT TO NSWC PANAMA CITY. This effort is focused on the development of a computational tool to simulate the far field bubbly wake of ships maneuvering in waves. The far wake solver is based on the numerical tools already available in the ship Boltzmann-based polydisperse two-fluid code REX, implementing the capability of computing the bubbly far wake under maneuvering conditions in waves using Cartesian grids and an unsteady Reynolds-Averaged Navier-Stokes (URANS) or large eddy simulation (LES) approach. The solution procedure will require solution of the ship flow and the near wake, where void fractions are high and active bubble entrainment breakup and coalescence occur, saving periodically portions of the near wake solutions that are then used as inputs for the far field wake. Implementation of these near wake solutions as internal boundary conditions for the far field wake will be performed using overset grids. The project anticipates transition of the code and support to the Naval Surface Warfare Center in Panama City, FL.
