Paper Number: SNAME-CSYS-2019-002
... displacement effect. Its time-stepping procedure has free convection and rollup of vortex wake elements providing non-linear lift properties and includes a number of modeling techniques for treating "real world" effects, such as flow separation and wave breaking. The free surface wave development uses a non...

... Conventional transom-hung rudders are often used on small sailboats because of their simplicity compared to rudders mounted under the hull; however, they present substantial performance penalties, including (1) the rudder is more likely to ventilate by drawing air down from the free surface, (2...

...-scale free-surface flows as found e.g. in naval architecture. This holds especially for the flow around typical modern yacht hulls, often planing, sometimes with surface-piercing appendages. Particular challenges include, but are not limited to, breaking waves, sharpness of interface, numerical...

... it is not uncommon to incorporate lifting or swing keels to reduce draft at specified times. The effects on aspect ratio and stability are relatively easy to approximate for such a vertical shift in volume, the effects on the free surface are much more difficult to accurately predict. For this purpose some novel...

... Hydrofoils operating at shallow depths ( e.g. keels and rudders) will be affected by the interactions between the lifting surfaces and the free surface. This problem is approached computationally and experimentally by examining the simple case of a surface-piercing hydrofoil operating at steady...
