... boundary layer, giving a region of recirculating reverse flow (O Meara & Muller, 1987). This type of bubbles typically occurs on thin foils and reattachment is due to the laminar-to-turbulent transition of the separated shear layer (Crabtree, 1957); in this case they are called Laminar- Separation Bubbles...

... and drag transition onset momentum thickness Reynolds coefficients from the RANSE calculations have been R~ e ,t number tU0/ compared with experimental data and results from the 2D- boundary layer code XFoil, showing reasonable RT local transition onset momentum thickness agreement. The method then has...

... Achievement of laminar boundary layer flow over sailboat appendages offers great potential for increased boat speed. Although some measurements of turbulence intensities and length scales in the upper ocean are available, it is unclear whether the local effects of wave action, high particulate...

... components through the use of a "moving" computational grid which conforms to the exact wetted surface area of the hull. Use of a full field approach, whereby the entire flow domain is discretized, permits the simulation of the boundary layer and wavemaking interaction as well as the onset of vortex...

... In this paper, foil and planform parameters which govern the level of viscous drag produced by the keel of a sailing yacht are discussed. It is shown that the application of laminar boundary-Layer flow offers great potential for increased boat speed resulting from the reduction in viscous drag...

These results include the shapes of the wakes and a typical chordwise pressure distribution. generate lift vorticity planform velocity field boundary layer lifting...
