Spiral-like structure of jet in a cross-flow

Ivana Milanovic, associate professor of mechanical engineering, CETA, published the research paper, "Unsteady wake vortices in jets in cross-flow," in the Journal of Visualization. The paper was co-authored with Khairul Zaman and Timothy Bencic of the NASA Glenn Research Center.

Unsteady wake vortices of jets in cross-flow were investigated in order to (1) advance the understanding of their origin and characteristics and (2) explore various excitation techniques for organizing and accentuating them. The key finding was that the wake vortices always originated from the lee-side of the jet where the jet efflux boundary layer and the wall boundary layer intersected.
