... on the validation of a Navier Stokes code for the same cases. The data obtained shows that there are significant Reynolds number effects on the flow in the wake due to the appendages. This effect is shown to be caused by the presence of the bossing and shaft which divert low speed hull boundary layer flow towards...

...) and the other with a conventional sharp edge. Both foils were designed to develop a lift coefficient of 0.20 and incorporate near-optimal chordwise distributions of loading and thickness. This paper presents measurements of lift and drag as functions of incidence and Reynolds number, as well as surface...
