• The model experiments using KOH solution/air-CO2 mixture gas jet are conducted to understand the effects of blowing conditions on reacting interfacial area in simulation of decarburization in the oxygen steelmaking. The fast pseudo-1st-order reaction regime is adopted by the chemical absorption theory to observe gas/liquid interfacial area which is the most important controlling parameter in the decarburization kinetics of high carbon regime. The result shows that the reacting interfacial area is greatly dependent on injecting gas flow rate, nozzle diameter, injection scheme and aspect ratio of the reacting volume. It is deduced that these effects are closely related with physical aspects of two-phase jet structure. An intuitive model for the jet effect on the reactivity is suggested.
