Low Re foil shaped profile modelling

Hi, I have to do some CFD analysis on the 2D shape seen below. I am interested in the lift and drag coefficients at angles of attack between +/- 6 degrees. I am planning on using ANSYS Fluent to perform this analysis but I have never used Fluent before (or any CFD software) and I think I need help. I tried some simulations on a NACA 0012 profile to compare with data in the book Theory of Wing Sections but the numbers are way off. Does anyone have any suggestions or comments to a new Fluent user?
The reynolds number I am operating at is approximately 425000 (speed of 0.5 mps in water). From what I have been reading on CFD it seems to be very difficult to model boundary layer transition from turbulent to laminar which this foil should be approaching. Thanks Tom |

Hi,
As a starting point, I would suggest having a go at the Fluent tutorials to get a feel of the interface and what can be achieved with Fluent. That is where I started and I found it quite useful. Tom. |

Thanks, I tried a few tutorials but I am still having problems at low reynolds numbers. Are there any different things that need to be done with the mesh or the viscosity model settings to account for the laminar-turbulent transition?
