Electro-optical phenomena in a gas-dispersed jet flow around a solid body
Annotation
In continuing studies [1–4] in which optics and electrification of particles colliding with a body around which a high-speed two-phase jet flows are considered, there was an attempt to explain the experimentally observed luminescence [5] of a conducting body, bombarded by microparticles, by the presence of a reverse unipolar current (from rebounded particles) exciting carrier-gas molecules. The process of charge acquisition by a particle in collision with a solid is complex: not only the value of the charge but even its sign are unknown in many cases [6]. A simple model is proposed for estimating the characteristic values of the reverse current density and the spatial distribution of the gas luminescence energy.
