The nonlinear evolution of those vortices was experimentally investigated on a concave-convex curved model. Experiment indicated that the linear state can be brief and the nonlinear regime dominates the primary instability. It also revealed that the developed mushroom-like structures are almost observed in that nonlinear stage. Hot-wire measurement of the velocity field allowed reconstruction of the vortex structure. The wall-normal and spanwise profiles of the streamwise component of the velocity showed simple and multiple inflection points. The profiles become more complex as the flow field becomes more nonlinear state. Spectral analysis of the spanwise profiles of the streamwise component show that only some modes suffice to represent the velocity field in the nonlinear regime.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
