The paper presents results of simulations of the flow around rudimentary landing gear using an improved version of the Partially-Averaged Navier Stokes model (PANS ζ-f ). The results are validated against time-averaged flow data such as pressure field and oil-film visualizations as well as quantities such as sound pressure level and surface pressure spectra that are relevant for aero acoustic noise generation. The results of PANS ζ-f are found to be in good agreement with the experimental data and observations. The PANS ζ-f presented here shows a clear advantage in the prediction of the flow compared with the reference LES simulation on an identical grid.
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.
