Expanding Channel

Influence of the jet flowing from a gas generator through a narrow slit on shock-wave structure of a stream in the channel of variable section is investigated. Influence of the size of a jet, density and speed of gas on an entrance, and also influence of oscillations of parameters of a jet is studied. Possibility of management of a supersonic stream of shock-wave structure in the channel with the help pulse and periodic an energy supply before a jet is investigated at negative feedback on pressure.

Modulation Theory

The structure of optical dispersive shock waves in nematic liquid crystals is investigated as the power of the optical beam is varied, with six regimes identified, which complements previous work pertinent to low power beams only. It is found that the dispersive shock wave structure depends critically on the input beam power. In addition, it is known that nematic dispersive shock waves are resonant and the structure of this resonance is also critically dependent on the beam power. Whitham modulation theory is used to find solutions for the six regimes with the existence intervals for each identified. These dispersive shock wave solutions are compared with full numerical solutions of the nematic equations, and excellent agreement is found.
