[HTML][HTML] Grid-point and time-step requirements for large-eddy simulation and Reynolds-averaged Navier–Stokes of stratified wakes

JQJL Li, XIA Yang, RF Kunz - Physics of Fluids, 2022 - pubs.aip.org
Estimates of grid-point and time-step requirements exist for many canonical flows but not for
stratified wakes. The purpose of this work is to fill in this gap. We apply the basic meshing …
