An approach to generating in §ow synthetic turbulence recently developed by the authors has been applied to zonal Reynolds-Averaged Navier Stokes (RANS) / Large Eddy Simulations (LES) of two complex turbulent §ows: §ow over a wall-mounted hump and hydrofoil trailing edge §ow, and to a LES of a §ow in a three-dimensional (3D) di¨user. The results show that the zonal RANS-LES approach with synthetic turbulence at the interface is in excellent agreement with experimental data for hump and trailing edge §ows. For the di¨user §ow, it is shown that results depend signi¦cantly on the RANS model used to provide averaged velocity and Reynolds stresses at the inlet.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
