Diffusive, Electrostatic Concentration of Disintegration Products of Inert Gases in Vortex Flow

Abstract

The problem of steady-state mass transfer of decaying products resulting from the disintegration of an inert gas is considered for a vortex pipe flow configuration under variable electrostatic fields. The flow configuration consists of two smoothly joined sections, one stationary and the other rotating with constant angular velocity. The products of disintegration are filtered out at far upstream, but are again generated by radioactive decay of flowing inert gas along the tube. Bulk concentrations result due to electrostatic force and diffusion. It was found that increasing the electrostatic charge caused a decrease in penetration; also, a decrease in charge profile was accompanied by an increase in potential since the particles become annihilated at the boundaries.
