AI based Larde Eddy Simulations for Turbulence in Fusion Reactors — •Robin Greif1, Frank Jenko1, and Nils Thuerey2 — 1Max-Planck Institute for Plasma Physics, Garching bei München, Germany — 2TUM Department of Mathematics, Garching bei München, Germany
In this talk, we demonstrate the effectiveness of using hybrid AI and numerical methods to produce practically endlessly stable turbulence simulations conserving physical, spectral, and statistical properties. Specifically, we look at the two-fluid Hasegawa-Wakatani model discretized in two spatial dimensions used for simulating drift wave turbulence in fusion reactors. The presented hybrid AI predictor-corrector model in the large eddy domain allows for reducing complexity by three orders of magnitude with negligible losses.
