problem in drag force calculation

March 12, 2009, 05:17

hi i am facing problems in claculating drag force over NACA0012 profile. problem specs are water flow over foil at 2m/sec velocity. angle of atack zero. as i knew from theoratical study at zero angle of atack the lift should be zero for NACA0012 as it is symetric. can u guide me in this regard. thanks

Yes, if you have symetrical foil then the zero lift ,it is showed at zero angle.
To find the drag, you will go in fluent: Report->Forces.
Here you will opt the specifications of your foil and you will push plot.
