Mathematical Modeling of Electrization of Particles of Acondensing Phase in High-Temperature Flow of Combustion Products of Rocket Engine

Influence of emitting nanoparticles concentration to the density of free electron in the thermal dusty plasma

“…The presence of particles in thermal plasma leads to their charging. One of the key mechanisms of charge acquisition by nano and microparticles in a high temperature gas is thermionic emission [3][4][5][6][7][8][9][10][11][12]. The acquisition of an electric charge by nanoparticles due to the emission of electrons strongly affects the electrophysical properties of the system as a whole and the electrical conductivity in particular.…”

“…The most common approach to describing the process of charging dust particles as a result of thermionic emission is the Richardson model [3][4][5]. This model is based on the Poisson-Boltzmann equation and the Richardson formula for the electron concentration near the surface of a solid [3]. An alternative approach is the description method based on the "jelly" model for condensed particles.…”
