The NACA four-digit wing sections define the profile by:[1]

For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord. Four-digit series airfoils by default have maximum thickness at 30% of the chord (0.3 chords) from the leading edge.

The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. The 15 indicates that the airfoil has a 15% thickness to chord length ratio: it is 15% as thick as it is long.

In this tutorial you will learn to simulate an Airfoil 3D (NACA 4412) using Ansys Fluent. In this tutorial we will use a polyhedral mesh which adapts better to the geometry and allows to obtain convergence in less time compared to the tetrahedral mesh.
