Generator geometry effect on wave dispersion of a gas in a liquid

Resumo

The influence of the channel diameter and length of the hydrodynamic oscillation generator on gas bubble dimensions in the case of wave dispersion of a gas in a liquid is experimentally investigated. The technique of measuring the bubble diameters based upon the computer analysis of the gas-liquid jet photos is presented. It is shown that on the gas flow rate range from 0.5 to 32 dm³/min the mean diameter of the gas bubbles produced by wave dispersers in water is estimated by an interval from 0.45 to 0.75 mm in optimum performance regimes.
