To the charging of sphere in a EHD gas flow
The interaction between conducting sphere and ions has been investigated in a presence of external electric field and electrohydrodynamic (EHD) gas flow. Gas is considered as weakly ionized under atmospheric pressure. Diffusion is assumed to be weak and the trajectory assumption is taken into consid...

Gas is considered as weakly ionized under atmospheric pressure. Diffusion is assumed to be weak and the trajectory assumption is taken into consideration. Ion currents are obtained analytically and investigated numerically for the collinear electric field and gas flow vectors. It is shown, that sphere charging regimes depend on the key parameter ξ± - the relation of ion drift velocity far away from sphere to gas velocity. So, the cases |ξ±| < 1 and |ξ±| > 1 yield to different charging regimes. For the potential flow, the ion current has been found analytically in continuous ξ± -parameter space. |
