Abstract

The unsteady Reynolds-averaged Navier- Stokes unstructured two-phase free surface capturing solver developed at the UT SimCenter at Chattanooga is applied to the simulation of a surface combatant with dynamic ship maneuvers. The solver utilizes artificial compressibility and a multiphase free surface capturing model to resolve the fluid motion in both the air and water regions and to manage complex free surface topologies. A general multielement unstructured mesh is utilized to achieve resolution requirements for the free surface interface, near-wall viscous spacing, and complex geometries. The approach is applied to surface ships with planar motion mechanism maneuvers. The evolution of the boundary layer and free surface with pure sway and pure yaw ship motions is presented. Validation of the results is provided by comparing predictions to force, moment, and PIV boundary layer data.
