Exascale Turbulence Simulations: From Fundamental Flows to Flight Scale Aerodynamics*

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.
