Abstract

The change in the electric charge of perfectly conducting and nonconducting particles of a suspension as a result of their collision with walls in a flow of the suspension is found. Criteria for the applicability of the obtained expressions to real particles are given. For the density of the electric current in rarefied suspensions consisting of a nonconducting gas and charged particles a condition is obtained that is satisfied for flow of a suspension at impermeable walls.
