| Abstract: | The theoretical analysis on bubble mass transfer process was made by the non reversible thermodynamics.Non steady state,steady state and equilibrium state and changing regulation were discussed.A relation of concentration near interface to flow velocity was proposed.Numerical simulation on the concentration field near gas liquid interface was made,and the results were in well accordance with the experimental ones. |
