Flow Resolution

Patent Awarded

November 14, 2024 by J. Poggie

My research group, in collaboration with Prof. Jewell's group at Purdue and Prof. Juliano's group at Notre Dame, was recently awarded a patent on a method for hypersonic inlet design. The patent reference is: M. E. Noftz, J. S. Jewell, A. J. Shuck, J. Poggie, A. N. Bustard, T. J. Juliano, "Inlets for Hypersonic Air-Breathing Vehicles and Design Methods and Systems Therefor," US Patent 12,134,997, Nov. 5, 2024. Much of the credit goes to graduate students Mark Noftz, Andrew Shuck, and Andrew Bustard. The patent came out of work funded by AFRL under the Multidisciplinary Hypersonics Program.

This is the second patent for our group. The first was: T. L. Pourpoint, U. Pandey, and J. Poggie, "Hypersonic Test Facility Using Nitrous Oxide," US Patent 11,779,882, Oct. 10, 2023.

FY 2025-2029 DoD Frontier Project

In collaboration with Lian Duan (PI) and Datta Gaitonde of The Ohio State University, our group has won a new DoD Frontier Project. The title of the project is "Physics of Pervasive Shock-Turbulent Interactions in Hypersonic Vehicle Propulsion and Control." The project will provide supercomputer time for fiscal years 2025-2029 to reduce prediction uncertainty for hypersonic shock-wave / boundary-layer interactions. The aim is, in turn, to help reduce the research and development cost of new hypersonic systems.

Our Purdue research team has now participated in three DoD Frontier Projects and one DoE INCITE Award, all large grants of supercomputing time to address issues in the computational physics of high Mach number flow. These projects have enabled training of graduate students in the use of supercomputers at the largest scale, and they have uniquely enabled the investigation of the physics of high Mach number flow.

For example, work with Nicholas Bisek and Ryan Gosse of AFRL under a DoD Frontier Project led to a 2015 article in Computers and Fluids on the effect of spatial resolution in high fidelity simulations of compressible turbulent flow. Computer hours provided by a 2016-2017 DoE INCITE Award led to a 2019 article with MS student Kevin Porter and a 2021 article with PhD student Akshay Deshpande in Physical Review Fluids. Their work investigated the effect of confining sidewalls on separation unsteadiness in a simplified inlet configuration. Work under a 2017-2022 DoD Frontier Project supported a study by PhD student Geoffrey Andrews of the effect of wind tunnel noise on hypersonic laminar-turbulent transition and a related study of the effect of incoming disturbances on separation unsteadiness.
