Nonlinear instabilities of boundary layer streaks is investigated experimentally. Extensive measurements visualizing the sinusoidal and varicose instabilities of streaky structures at the nonlinear stage of the breakdown process in boundary layer are presented. The flow behaviour in the course of spatial evolution of the streaky structures with a secondary(More)
We propose a type of lossless nonlinear polarizer, novel to our knowledge, a device that transforms any input state of polarization (SOP) of a signal beam into one and the same well-defined SOP toward the output, and perform this without any polarization-dependent losses. At the polarizer output end, the signal SOP appears to be locked to the input pump(More)
In this article we develop Poincaré ideas about a heat balance of ideal gas considered as a collisionless continuous medium. We obtain the theorems on diffusion in nondegenerate completely integrable systems. As a corollary we show that for any initial distribution the gas will be eventually irreversibly and uniformly distributed over all volume, although(More)
Traditional derivation of Gibbs canonical distribution and the justification of thermodynamics are based on the assumption concerning an isoenergetic ergodicity of a system of n weakly interacting identical subsystems and passage to the limit n → ∞. In the presented work we develop another approach to these problems assuming that n is fixed and n ≥ 2. The(More)
The presentation is focusing on the coherent features of a swept wing boundary layer. The three-dimensional flow of a swept wing is highly unstable with respect to longitudinal streamwise vortices, which, in turn, are subject to the secondary instabilities. The fact is that stationary vortex packets are most likely to be generated under natural flight(More)
We experimentally study Bragg-scattering four-wave mixing in a highly nonlinear fiber at telecom wavelengths using photon counters. We explore the polarization dependence of this process with a continuous wave signal in the macroscopic and attenuated regime, with a wavelength shift of 23 nm. Our measurements of mean photon numbers per second under various(More)
