Abstract

The spectrum of the coherent Rayleigh-Brillouin scattering (CRBS) of light by a rarefied gas is obtained by solving the Boltzmann equation numerically using the fast spectral method. The influence of the intermolecular potential on the CRBS spectrum is investigated and the accuracy of the prevailing Tenti’s s6 kinetic model is evaluated. Our numerical results show that i) the intermolecular potential has a great influence on CRBS spectrum when the Knudsen number is between 0.05 and 1 and ii) Tenti’s s6 kinetic model can only predict the line shape accurately for Maxwell gases at small Knudsen numbers.
