Abstract
En 中文
• Replace ROM spatial filtering with a data-driven stabilization operator (StabOp). • Learn StabOp via PDE-constrained optimization of target QoIs. • Construct linear, quadratic, and neural-network-based StabOps. • Embed StabOp into the Leray ROM to obtain a new stabilized ROM. • Validate StabOp on 2D and 3D under-resolved convection-dominated flows.
