Results of an experimental study of turbulent breakdown in gradient boundary layer at high freestream turbulence are reported.
For the first time it is shown that, like the flat-plate boundary layer, the wing boundary layer at high freestream turbulence
is modulated with streaky structures. One of possible mechanisms underlying the generation of turbulence spots in wing boundary
layer is modelled assuming the interaction of streaky structures with high-frequency waves. Qualitative and quantitative data
concerning the evolution of streaky structures in swqpt-wing boundary layer and in swept-wing boundary layer are presented.
Certain differences between the evolution of streaky structures in wing boundary layer and in flat-plate boundary layer are
revealed.

Experimental data concerning the influence of initial conditions at the nozzle exit on the structure and development characteristics
of round jets are reported. Features in the development of laminar and turbulent round jets emanating from variously elongated
nozzles at identical Reynolds numbers are revealed. Smoke visualization pictures obtained for jets formed under different
initial conditions (with different distributions of mean and pulsating flow velocities at the nozzle exit) are discussed.
It is shown possible to make the zone of laminar flow in the jet stream more extended, and to delay the jet turbulization
process in space, by making the flow-velocity profile more parabolic at the exit of elongated nozzle. Features in the development
of vortical structures in a jet under an acoustic action are identified. It is shown that, for a turbulent round jet to be
produced right at the nozzle exit, the nozzle length must be increased in excess of a certain value so that to provide for
spatial growth of turbulent boundary layer thickness, finally ending in the formation of a fully turbulent flow velocity profile
across the channel.
