Structure and Interpretation of Surface Flows

J Green 1969

 In the wind tunnel and production CFD environments, visualization of the fully 3D flow is a luxury rarely granted. For wind tunnels, even a 2D surface flow visualization is an expensive, messy, and incomplete tool. Learning to interpret and mentally visualize the flow structure is a critical skill.

So, in the spirit of a great book, SICP, the following documents from ONERA provide a wonderful explanation of the Structure and Interpretation of Surface Flows. After reading through these, you should be able to mentally visualize the 3D flow corresponding to the above image.

Presentation: Aircraft Flight Dynamics with a Non-Inertial CFD Code

Aircraft Flight Dynamics with a Non-Inertial CFD Code
AIAA 2005-0230

This project was presented as AIAA 2005-0230 and concerns coupling a non-inertial CFD code with a 6 DOF (degree of freedom) rigid body dynamics simulator. Quaternions are used for attitude orientation. The result is a computational aircraft flight dynamics simulation. The paper shows flight maneuvers such as rolls, loops, and thin-strip Magnus lift production.
