Pictures of an Initial Separation (2D)

Pictures by Shankar Subramaniam (S. Shankar). This work was made possible by support of the Air Force Office of Scientific Research.

The pictures show a cross section of a cylinder that experiences a gust of air coming from the left. The blue and red colors indicate the boundary layer, consisting of air that has been retarded by the cylinder surface. To be precise, when the cylinder surface retards the air, it gives it a spinning motion called vorticity: the color indicates how fast the air is spinning around and in what direction.
