The shock wave structure in a dense electronegative gas containing conductive particles

The structure of a flat shock wave in an electronegative gas containing a rarified suspension of small metallic particles (macroparticles) is considered. When heated due to thermal electron emission, the particles are ionized in the shock compression that occurs in the carrying gas. The emitted electrons adhere to the electronegative neutral molecules, which gives rise to the formation of a multicomponent gas mixture composed of ions, electrons, neutrals, and positively charged macroparticles. The profiles of the corresponding variables are calculated within the Navier-Stokes approximation. The reaction of sticking is analyzed with the use of chemical kinetics equations. The calculations were performed for the case of air, which assumed by binary mixture of molecules O2 and N2. The initial temperature and the Mach number of the oncoming flow are T = 500 K and M = 3.
