Exascale Turbulence Simulations: From Fundamental Flows to Flight Scale Aerodynamics
ORAL
Abstract
This talk will provide an update on two Argonne Early Science Program (ESP) projects. The first is a Simulation ESP where prior delayed detached eddy simulations of flow control on a vertical tail at a chord Reynolds number of 325k were validated against experiments are being extending to flight scale (53 times higher Reynolds number). The second is Data and Learning ESP focused on: 1) data compression, 2) turbulence modeling improvement from machine learning, 3) uncertainty quantification and multi-fidelity modeling, and 4) in situ data analytics. Progress made towards these ambitious goals will be shared as well as future plans and needed developments.
*This work is supported not only by Argonne National Labs through the aforementioned ESP projects but also by the National Science Foundation (NSF), award number CBET-1710670 and by the National Aeronautics and Space Administration (NASA), award number 80NSSC18M0147. Resources of the Argonne Leadership Computing Facility, a DOE Office of Science User Facility, and of the NASA HECC facilities were used.
