PANS of Rudimentary Landing Gear
Paper in proceedings, 2011

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 z- 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 z- f are found to be in good agreement with the experimental data and observations. The PANS z- f presented here shows a clear advantage in the prediction of the flow compared with the reference LES simulation on an identical grid.
