NACA foil OpenFOAM case files

OpenFOAM (3.0.x) case files for simulating NACA foils. Wikipedia's NACA 4-digit airfoils (http://en.wikipedia.org/wiki/NACA_airfoil)

Dependencies

• Python
• NumPy
• pandas
• matplotlib

Note: All dependencies are included in the Anaconda Python distribution. Python 3.5 is recommended.

Usage

To run a single case, execute

./Allrun {foil} {alpha_deg}

For example, to simulate the flow around a NACA 0012 at 8 degrees angle of attack, run

./Allrun 0012 8

To automatically simulate multiple angles of attack, execute

python paramsweep.py

To plot the results for multiple angles of attack, run

python plot.py
