SO2 bubble formation at an orifice submerged in water

To estimate mass transfer rate during bubble formation at an orifice, a the oretical model is proposed for soluble gas bubble formation in liquid by mo difying the non-spherical bubble formation model. The absorption rate from pure SO2 gas bubble to water is experimentally measured as well as bubble s hape and growth rate. Mass transfer from the gas-liquid interface during bu bble growth is described well by the penetration theory. Experimental bubbl e shape, bubble volume at its detachment from an orifice, growth rate and m ass transfer rate are estimated well by the present model.
