THE ROLE OF EXTERNAL DISTURBANCES INLAMINAR-TURBULENT TRANSITION,ty level, external perturbations initiate transition through receptivity process, i.e. by exciting instability waves, but without affecting linear and subsequent nonlinear amplification rate. At moderate to high intensity level, however, external disturbances may directly alter the instability prope

LOCALISED INSTABILITY IN UNSTEADY SEPARATION BUBBLES,e unsteady boundary layer is created by controlled temporal and spatial variations of the velocity external to the boundary layer. We present results of the evolution of instability in different temporally varying flows in a shallow angle diffuser. Depending on the extent of reverse flow in the boun

THE PECULIARITIES OF DEVELOPMENT OFFORERUNNERS ON LONGITUDINAL STRUCTURES FRONTS IN THE BOUNDARY LAurbations, that is, “forerunners” occurring near the fronts of the streamwise disturbances were detected. Their characteristics and dynamics were clarified revealing similarities of the disturbances with boundary-layer instability waves.
