Techniques for improved statistical convergence in quantification of eddy diffusivity moments
Dana Lynn Ona-Lansigan Lavacot, Jessie Liu, Brandon E. Morgan +1
While recent approaches, such as the macroscopic forcing method (MFM) or Green's function-based approaches, can be used to compute Reynolds-averaged Navier--Stokes closure operator…

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…

Fast Macroscopic Forcing Method
Spencer H. Bryngelson, Florian Schäfer, Jessie Liu +1
The macroscopic forcing method (MFM) of Mani and Park and similar methods for obtaining turbulence closure operators, such as the Green's function-based approach of Hamba, recover…
