WebThe no-slip boundary conditions are adopted on the surface of the pipeline, i.e., u = 0, v = 0 and ∂ p /∂ n = 0. The turbulence energy k is set to be zero on the pipeline surface, and ω = 6Δ / υ with Δ being the distance of the first layer meshes adjacent to the pipeline surface to the pipeline surface. WebSubmarine technology is an undisputed cornerstone for coastal defenses around the globe. Not only does it enable a naval force to operate with covertness, but also bestows a nuclear power with second-strike capabilities. One of the main areas of research in submarine and ship design is the identification of optimum ship performance design parameters. For that …
