Computational fluid dynamics simulations of ship airwake
Computational fluid dynamics (CFD) simulations of ship airwakes are discussed in this article. CFD is used to simulate the airwakes of landing helicopter assault (LHA) and landing platform dock-17 (LPD-17) classes of ships. The focus is on capturing the massively separated flow from sharp edges of blunt bodies, while ignoring the viscous effects. A parallel, finitevolume flow solver is used wit...
متن کاملAirwake simulations on an LPD 17 ship
The flow over the San Antonio class LPD 17 ship is simulated using Computational Fluid Dynamics (CFD) and parallel computers. Both steady-state and time-accurate results are presented for two yaw cases. The computations are done for inviscid flow with no turbulence modeling. Although the flow is highly turbulent and boundary layer effects may not be insignificant, the essential features, such a...
متن کاملCommunity structure of corals and reef fishes at multiple scales.
Distributions of numerical abundance and resource use among species are fundamental aspects of community structure. Here we characterize these patterns for tropical reef fishes and corals across a 10,000-kilometer biodiversity gradient. Numerical abundance and resource-use distributions have similar shapes, but they emerge at markedly different scales. These results are consistent with a contro...
