“My area of research focuses on collecting detailed experimental data on the 3D turbulent boundary layer separation over a smooth bump. This is a good test case for Computational Fluid Dynamics (CFD) models, which typically struggle to accurately predict performance in this flow regime. The data from this test, along with detailed documentation of the experimental set-up and facility, initial conditions, and flow qualities, will help to tune CFD models to better predict the separation over this surface. These improved models can then be applied to more complex cases, such as commercial aircraft or spacecraft design applications. Increasing the quality of CFD predictions reduces the experimental testing required to validate the performance of this vehicles, which will speed up the development timeline and drastically decrease costs, allowing for more innovation in the industry.

Stefan Povolny is a fifth-year Ph.D. candidate and earned his undergraduate degree in Aerospace and Ocean Engineering from Virginia Tech in 2015. He is a student member of Tau Beta Pi, Phi Kappa Phi, and the AIAA.
In 2016, he spent the summer working at Orbital ATK, conducting trade studies on satellite structure using Femap with NX Nastran. There, he also assisted in preparation of vibrational testing of flight hardware and established compliance of shock response spectrum data. In 2019, he worked at Lawrence Livermore National Laboratory, identifying sources of error in shock simulations using the material point method and Developing, testing and verifying mitigation strategies for said sources of error.
Povolny has been awarded the Martin Marietta Aircraft Fellowship, and the Charles C. Walts Fellowship. Upon graduating, he hopes to work on exotic materials and constitutive modeling research at a national lab.
I research how numerical methods can be used to simulate exotic material systems. Specifically, I analyze the behavior of highly porous ultra high temperature ceramics (UHTCs) using the material point method. UHTCs stand to be a revolutionary material in the development of sharp geometries, e.g. leading edges, on hypersonic vehicles. However, they suffer from a relatively high density. This is mitigated by the introduction of porosity, but doing so affects the characteristics of the UHTC. My research seeks to characterize this effect. One impact is that such numerical models allow researchers here at VT and elsewhere to intelligently design UHTC-related experiments before investing precious resources into actual testing. On a more ambitious scale, the benefits to hypersonic flight that UHTCs could offer include the development of aircraft capable of traversing the globe in a matter of a few hours.”
