The primary goal of this project is to demonstrate that a computational capability is available to confidently predict the airwake about ship superstructures. The unstructured mesh-based incompressible flow solver, FEFLO, is used to compute this unsteady flow. Computed results are compared with wind tunnel model test experimental data at select locations and shows good agreement. The effects of tunnel walls and heading are studied. The unsteady flow field from the computations can serve as input to the Manned Flight Simulator (MFS) and can also be navigated in a virtual immersive environment in the Grotto at the Naval Research Laboratory. 收起
