“…From Table 2 it follows that if there were no oxides of Al, then the distribution N L (x) for x < x a * would be determined by reaction (12). A different picture is observed in the wakes in experiment Nos.…”

This paper reports results from measurements of the electron concentration in wakes behind aluminum spherical models flying at velocities of 2-5 km/sec in air-xenon mixtures at a total pressure in the ballistic track of 20-100 torr. The heating of the models moving in the ballistic track and aluminum ablation from their surfaces were calculated. The rate constant of electron attachment to microparticles is found, and it is shown that it depends on the fraction of xenon in the mixture. The dependence of the coefficient of electron accommodation to the microparticle surface on the xenon concentration in the mixture is obtained and explained from a physical point of view.Key words: ballistic experiment, coefficient of electron attachment to aluminum oxide microparticles, air-xenon mixture, electron accommodation coefficient.

“…The theory of a nonequilibrium turbulent far wake [12] is used. At x/d > 50, the pressure along the wake axis is close to the incident flow pressure, and the temperature along the axis of the far wake is calculated by the formula [1]…”
