This paper discusses the use of two variations on New-ton's method, quasi-Newton and full-Newton, for the solution of the Euler equations on unstructured triangular grids. The ILU(n)-preconditionedâ€¦ (More)

An Autonomous Underwater Vehicle refuel station is proposed. The power source is located on board a surface vessel, while the AUV is serviced at depth. The structure which connects the two craft isâ€¦ (More)

The pursuit equations in two-dimensional space are examined, and then parametrised in terms of relative velocity and initial range. Several inferences about the behaviour of these equations areâ€¦ (More)

The selection of an external pressure vessel material is described. Failures in the rupture and buckle modes are discussed, as well as the problem of submarine hull hydrostatics. A spherical geometryâ€¦ (More)

A fast Newtonâ€“Krylov algorithm is presented that solves the turbulent Navierâ€“Stokes equations on unstructured 2-D grids. Themodel of Spalart andAllmaras provides the turbulent viscosity and isâ€¦ (More)

A proposal for a buoy station for AUV refuel is described and depicted. An algorithm to calculate the forces on, and displacements of the buoy is selected. The buoy is to be funded and manufacturedâ€¦ (More)
