Abstract

In this work the dual mesh approach, a highly wall-
refined one for the RANS overlapping a more ho-
mogenous and isotropic mesh for the LES, was ap-
plied for the first time to a natural convection flow
which is a high Rayleigh number differentially heat-
ed cavity flow. The dual mesh framework of Tunstall
(2016) was found to perform satisfactorily in this
flow provided that the criterion that determines
where the RANS simulation drives the LES and vice
versa is defined based on the ratio of the LES re-
solved to the LES total turbulent kinetic energy.
