In this paper we present a numerical method for simulation of gas flows at micro- and nanoscales based on solving of relaxation-type kinetic equations with the the discrete ordinate method and a high-order shock-capturing scheme. The method is used for simulation of such classical problems as the shock-wave structure and the supersonic flow over a flat plate as well as for investigtion of shock wave propagation in a microchannel. The results obtained are compared with Navier-Stokes and DSMC solutions and experimental data.

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.
