Abstract

The shock-wave structure close to a wall in pure argon and binary mixtures of noble gases (argon–helium, xenon–helium) is investigated experimentally and numerically in the shock-wave Mach-number range 2·24 ≤ Ms ≤ 9.21. Measured and calculated density profiles are compared, and some conclusions are drawn about the accommodation at the wall and the intermolecular force potential.

For binary gas mixtures only a few results are presented. Weak argon signals of the electron-beam-luminescence method on the experimental side and the computer time needed for the numerical simulation allowed the treatment of a few parameter combinations only.
