Problem Specification

A wing with a NACA 0012 airfoil section has a chord of 1 meter, a span of 1 meter, and a thickness of 0.01 meter. The wing is made of Aluminum 6061-T6. If air moves at 987.84 km/hour around the airfoil, find the velocity vectors of compressible flow over the airfoil.

Verification

In order to verify that the simulation is accurate, it must be compared to a study that is similar in nature. We will compare the AIM results with results from Stanford University’s Aerospace Design Lab. In that study, users were expected to become familiar with performing an optimal space design in a 2D space. The airfoil used was also the NACA 0012, which makes this a perfect example to compare ours to. Below is the pressure contour that was plotted as a result of the Stanford tutorial, which can be directly compared to the pressure contour found in the previous section.
