Ellipsoid-cylinder model
Abstract
The data presented in this contribution were obtained in the F2 subsonic wind tunnel of the ONERA Fauga-Mauzac Center. The objective of this work was to obtain detailed experimental data on a separated vortex flow. The model shape has been chosen to be as simple as possible in order to facilitate the mathematical modeling. This model has been defined after preliminary studies in a water tunnel. The present document reports the results obtained with an axisymmetric model at incidence. Attention has been focused on the boundary layer evolution in the zone of separation and on the mechanism leading to the formation of a well detached primary vortex. The flow has been investigated in great detail by using several experimental techniques: surface flow visualizations, surface pressure measurements, field explorations by multihole pressure probes, and an LDV system.
