Fast macroscopic forcing method

Spencer H. Bryngelson, Florian Schäfer, Jessie Liu, Ali Mani

Abstract: Highlights•Fast Macroscopic Forcing Method analyzes closure operators for fluid flows.•The new method has cost complexity improvements over existing methods.•Cost improvements mean only few full resolution simulations required for flow closures.•Examples provided for RANS-like turbulence closures.•Can construct closure operators for other PDEs with hard-to-resolve scales.
