Part of the IUTAM Symposia book series (IUTAM)

Summary

The experiment on the secondary instability associated with Goertler vortices in rotating boundary layer is presented. The flow visualizations and hot-wire measurements show the instability with respect to spanwise disturbance resulting in the wavelength modulation. The instability with respect to streamwise disturbance appears downstream in the form of horseshoe and wavy modes, whose selection is related to the modulated spanwise wavelength of the nonlinear Goertler vortices.
