Mass transfer coefficients inside single rising bubbles are measured in the system SO 2 , N 2 —H 2 O by using a photographic technique. The differential equations which govern the phenomena, including internal toroidal circulation inside the bubble, are also presented. Assumptions are incompressible, steady, irrotational outside flow and inviscid, steady, axisymrnetric inside flow. From the mass transport viewpoint, restrictions are: binary dilute mixture and axial symmetry. The theoretical solution is presented as Sh vs. Pe and a comparison with experiments shows good agreement. Theoretical predictions for a stagnant fluid inside the bubble were also compared with the experimental results.
