Ivana Milanovic, professor of mechanical engineering, CETA, presented a research paper at the American Society of Mechanical Engineers (ASME) Heat Transfer, Fluids Engineering, & Nano-, Micro- and Mini-channels Conference (HTFNMM2012) in July 2012 in Puerto Rico.
The HTFNMM Conference brought together international researchers
and engineers focusing on heat and mass transfer and fluid flow in
a variety of applications. The objectives of the meeting were to
provide a forum for the presentation of state-of-the-art research
and opportunities for technical interactions among
The research paper, "Effect of Artifical Perturbation on Unsteady Wake Vortices in Jets in Cross-Flow," was co-authored with Khairul Zaman and Timothy Bencic of NASA Glenn Research Center. The experimental study examined unsteady wake vortices of jets in cross-flow and explored the possibility of periodic perturbation of these vortices with oscillating tabs. Tab oscillation introduced periodicity of the flow manifesting by side-to-side oscillatory motion of the entire flow field with varying phase.
Milanovic also co-organized the 11th Symposium on Fundamental Issues and Perspectives in Fluid Mechanics and 5th Symposium on the Transport Phenomena in Mixing.
