Abstract

A simple conductivity method for the measurement of void fractions in gas-electrolyte dispersions is described. The experimental correlation between the effective conductivity of the dispersion and the gas voidage is in very good agreement with the well-known Maxwell equation. The simplicity and versatility of the method are demonstrated in the experimental study of an electrolytic cell with simulated gas evolution. The measured gas void fraction has been correlated with the superficial gas and electrolyte velocities in accordance with a theoretical correlation given by Nicklin.
