As a fundamental study on the dissolution process of gas into molten metal, a model experiment was done to reveal the effects of liquid flow velocity and turbulence intensity near a gas-liquid interface on the mass transfer coefficient from gas phase. To obtain the mass transfer coefficient, the dissolution rate of CO2 gas into water was measured by using a lance under several flow conditions of different flow velocities and different turbulence intensities. On the basis of the present experimental results, an empirical correlation for the mass transfer coefficient was proposed as a function of the turbulence intensity in addition to the usually used Reynolds number and Schmidt number. Another correlation for the mass transfer coefficient under stagnant conditions was proposed as a function of the diffusion coefficient of CO2 gas into water.
