Web3 Mar 2016 · We report wall-resolved large-eddy simulations of an axisymmetric body of revolution with appendages. The geometry is that of the DARPA SUBOFF body at 0 yaw angle and a Reynolds number equal to $\mathit{Re}_{L}=1.2\times 10^{6}$ (based on the free-stream velocity and the length of the body). The computational grid, composed of … WebThe geometry used in the present work is an idealized submarine hull (DARPA SUBOFF without appendages) at zero angle of pitch and yaw. The computational domain is chosen to avoid confinement effects and capture the wake up to fifteen diameters downstream of the body. The unstructured computational grid is designed to capture the fine near-wall ... 3d怎么渲染全景图

WebFigure 1. Fully appended SUBOFF generic nuclear submarine hullform. The SUBOFF model has been tested in a number of configurations, including the unappended axisymmetric body and with a variety of appendages [6]. In this set of experiments and CFD simulations, only the unappended axisymmetric body was studied. Web24 Aug 2024 · The SUBOFF model is an axisymmetric hull with a total length of 4.356 m and a maximum diameter (D) of 0.508 m. The SUBOFF model has a sail above the hull, its leading edge is located at 0.924 m (1.820D) from the bow and the trailing edge is 1.293 m (2.545D) away, so the total length of the sail is 0.368 m (0.724D). ... WebThe near field around a 1:20 of the DARPA Suboff moving in a strongly stratified flow was simulated. The effects of pycnocline, submarine depth, and speed on the free surface wave and internal wave were analysed. The results demonstrate that the presence of pycnocline can increase the intensity of divergence and convergence at the free surface. 3d恐龙博物馆
