Equations are presented for calculation of the field strength distribution across the interelectrode space of a capacitor as a function of the concentration and size of the charged particles. The distribution of particle concentration is conducted in the steady-state flow of a fluid electroaerosol formed on the free surface of a bubbling layer and inoving along the electrical field lines of force. Computation formulas are derived for the mean concentration of particles as a function of their size, the field strength, and the flow of the bubbling gas
