Targeted computation of nonlocal closure operators via an adjoint-based macroscopic forcing method
Jessie Liu, Florian Schäfer, Spencer H. Bryngelson +2
Reynolds-averaged Navier--Stokes (RANS) closure must be sensitive to the flow physics, including nonlocality and anisotropy of the effective eddy viscosity. Recent approaches used…
