​About the Lecture

​Aerodynamic drag and heat transfer must be accurately predicted to design a high-speed vehicle. To do so requires a physical understanding of supersonic/hypersonic turbulence and, relating to weather encounter, multiphase flow physics. The first part of the talk will discuss efforts to obtain data to support Morkovin’s hypothesis, which is foundational to our understanding of high-speed turbulence. It states that “we can expect with confidence that the essential dynamics of these supersonic shear flows will follow the incompressible pattern.” We will present new data supporting this hypothesis at Mach 6. In the second part of the talk, we will present new aerobreakup data that were obtained by observing the flow about a railgun-launched projectile as it processed an ultrasonically levitated water drop. Linear- and nonlinear-stability analyses were made and the results are compared to computations.

​About the Speaker

​Nick Parziale is the George Meade Bond Professor of Mechanical Engineering at Stevens Institute of Technology, where he has been a faculty member since 2013. He earned his Ph.D. in Aeronautics from the California Institute of Technology in 2013. His group’s research focuses on supersonic and hypersonic aerodynamics, including boundary-layer instability, turbulence, and reacting/multiphase flows including aerobreakup and impact. Nick’s group has been recognized with the AFOSR (2016) and ONR (2020) Young Investigator Program awards, four Air Force Summer Faculty Fellowships (2014-2017), and the Presidential Early Career Award for Scientists and Engineers (PECASE) in 2024.

​​​​​​​About the Mechanical and Aerospace Engineering Seminar Series

​​Requirement for Students Enrolled in ME-GY9990 (PhD +Masters Students) : Students are required to attend more than 80% of the seminars. We will have an average of 1 per month during the semester, so students could miss only one seminar for the Spring 26 semester.

​​​​​​​​This series offers a unique opportunity to engage with a broad range of topics at the forefront of mechanical engineering, including robotics, bioengineering, artificial intelligence in science, disaster modeling, and solid and fluid mechanics. Each session features distinguished speakers from leading institutions around the world, providing valuable insights into current research challenges and innovations across the field.
