Time Accurate Computational Simulations of Ship Air Wake

Abstract

Time accurate computational fluid dynamics (CFD's) calculations were performed to characterize the unsteady nature of the air wake produced by a U.S. Navy LHA class ship. A series of wind-over-deck (WOD) conditions were examined. It was found that the general character of the air wake changed dramatically as the WOD angle changed. The air wake was also found to be highly unsteady or "turbulent" but also contained some strongly periodic features. The CFD simulations were done at full-scale conditions with second order time accuracy using the COBALT CFD code. COBALT is an unstructured grid, Navier-Stokes solver.
