... for highly cambered plates, specifically circular arcs, comparable to horizontal sections of downwind yacht sails. Measurements are undertaken at positive incidences below deep-stall for Reynolds numbers ranging from 53,530 to 218,000 in a towing tank and a water tunnel to devise a blockage correction...

... wires are commonly used on tank test models to fix the location of transition, which would occur further aft at model scale compared to full scale, because of the lower Reynolds number (Re) in the former situation. If we assume that these vessels could travel at say 10 knots or 5 m/s, then based...

... limitations to this work. Most notably, the models are small, so it was not possible to match Reynolds number with full-size sails, and the models were hard sails tested in isolation from the rest of the rig and hull. In spite of these limitations, we believe the results provide useful information...
