Sail aerodynamics
For those interested in the aerodynamics of sails: we have posted a new
article " Flow simulation around sails with CFD" at http://www.wb-sails.fi/news/470StreamAnim/index.htm |

Do you happen to know which way the wind is blowing? I can't see the boats well enough to tell. BTW I trust you've read Bethwaite's "High Performance Sailing"? Andy |

Do you happen to know which way the wind is blowing? I can't see the boats well enough to tell. The helicopter is just under the starboard bow of the closest boat. The wind is coming from a point to the right (as we see it) of the picture. If we could measure the exact angle of the boat, to the vortex stream there would probably be a limited number of solutions for the wind strength, true wind angle, apparent wind angle and boat speed which would produce the pictured result.
