• A vertical bubbling jet was generated in a cylindrical mercury bath by injecting air from the bottom through a centric nozzle. Gas holdup α and bubble frequency fB in the mercury-air vertical bubbling jet were measured by means of an electro-resistivity probe. On the basis of the present and other previously published experimental results, correlations for α, fB and mean bubble rising velocity [u.gif]B were derived for bubbling jets with a density ratio ρl/ρg between 780 and 11 000 as functions of Qg, dn, σ and ρl/ρg, where Qg is the injected gas flow rate, dn is the inner diameter of Nozzle, σ is the surface tension of liquid, ρl is the density of liquid and ρg is the density of gas. These correlations were found to be valid in the vicinity of the nozzle exit where the expansion of gas due to static pressure change was negligible.
