Abstract
An analytical solution for the primary potential and current distribution around a spherical bubble in contact with a plane electrode is presented. Zero at the contact point, the current density reaches only 1% of its undisturbed value at 30% of the radius from that point and goes through a shallow maximum two radii away. The solution obtained for spherical bubbles is shown to apply for bubbles having contact angles smaller than 17.5°. The incremental resistance caused by dilute arrays of bubbles is evaluated.Keywords
