Hello everyone,
I'm new to this forum so please move this thread if it is in the wrong spot.
I am a student studying a masters in Civil & Structural Engineering at the university of leeds. For my final years dissertation i chose to do some computational fluid modelling of the aerodynamics of sails. A part of this involves creating a virtual wind tunnel, and blowing air through a 2d cross section of a sail (in plan view).
I am a laser sailor, race regularly but not excessively and finish usually in the 2/3 of the fleet at club racing, so I know how things work reasonably well.
For each point I think I have the correct sail shape in plan view.
Here's my attempt:
Close Hauled
Maximum camber (0-9):3
Max camber pos. (0-9): 2
Thickness (0-99): 0
Point size: 4
Beam Reach
Broad Reach
Am I correct? Using the link, what do you think the three points should be set at? Use the sliders to change the aerofoil's shape - make thickness zero (negligable) and ignore the sliders below "# Points".

- To create the 2d sail geometry I use a program called Gambit.
- To run the virtual wind tunnel, I will use a piece of software called Fluent (v popular with the Americas Cup)
- In order to create the sail curve I use this online Java applet: http://www.ppart.de/aerodynamics/profiles/NACA4.html.
