Ivana Milanovic, professor of mechanical engineering, College of Engineering, Technology, and Architecture (CETA), presented a research paper at the American Society of Mechanical Engineers (ASME) Heat Transfer, Fluids Engineering, & Nano-, Micro- and Mini-channels Conference (HTFNMM2012) this month 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 participants.
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.
