Presented By: Aerospace Engineering
AE Chair's Distinguished Seminar Series: "Characterization of Previously Inaccessible Supersonic and Hypersonic Flows"
Asst. Professor Nick Parziale, Stevens Institute of Technology, Department of Mechanical Engineering
Asst. Professor Nick Parziale, Stevens Institute of Technology, Department of Mechanical Engineering
Reacting/high-speed flow investigation with non-intrusive optical techniques permits researchers to probe fluid flows in harsh or otherwise previously inaccessible environments. New insight into the flow physics of the wicked problems in supersonic and hypersonic flows can be had with the clever application of recent advances in laser, camera, and electronics technologies. In this talk, two examples of such efforts will be discussed. The first example is the previously unexplored boundary-layer instability on a slender cone in hypersonic, reacting flow which was characterized by the implementation of focused laser differential interferometry (FLDI). The second example is a laser-based technique that measures velocity in a high-speed gas which utilizes trace amounts of krypton for the purposes of flow tagging called Krypton Tagging Velocimetry (KTV). Example results are given for a study of supersonic shock-wave/turbulent boundary-layer interaction and characterization of Arnold Engineering Development Complex (AEDC) Hypervelocity Tunnel 9 at Mach 10 and Mach 14.
About the Speaker...
Nick’s current research interests include high-speed and reacting flows, chemical-thermodynamics, and heat transfer with applications in the fields of defense and energy/sustainability. Current projects include novel methods of high-speed flow velocimetry, hypersonic boundary-layer instability, shock-wave/boundary-layer interaction, biomass to bio-oil conversion, and nitrogen-based fuels research.
Nick received his BS in Mechanical Engineering from SUNY Binghamton in 2008, then received his MS and PhD degrees in 2009 and 2013 from the Caltech Graduate Aerospace Laboratories (GALCIT). In 2013, he was a PostDoc at Caltech and then a Visiting Assistant Professor at Stevens. Currently, Nick is currently an Assistant Professor (2014-present) in the Mechanical Engineering Department at the Stevens Institute of Technology in Hoboken, New Jersey. Nick spent four summers, from 2014-2017, as an Air Force Summer Faculty Fellow at AEDC White Oak in Silver Spring, MD.
