Approximate Analytical Models of Shock-Wave Structure at Steady Mach Reflection

In this study, we obtain the comparative analysis of methods of quick approximate analytical prediction of Mach shock height in planar steady supersonic flows (for example, in supersonic jet flow and in narrowing channel between two wedges), that are developed since the 1980s and being actively modernized now. A new analytical model based on flow averaging downstream curved Mach shock is proposed, which seems more accurate than preceding models, comparing with numerical and experimental data.

The aim of the investigation is to understand the shock-wave structure of the supersonic jet exhausting from a beveled nozzle. Results of investigation are presented as cross section Pitotpressure fields. This data can be used for verification of CFD results. The experiment was complemented by numerical simulation with using of the program packet ANSYS Fluent. The satisfactory qualitative agreement was obtained

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.
