Abstract
Theoretical studies have been made on the flow of gas and the mass transfer in the system with the immobile gas-liquid interface, in order to discuss the mass transfer between an impinging jet of gas and a liquid iron.
The upwind difference scheme has been used for formulation of the finite differential equations of the velocity of gas and the concentration of diffusing gas. The solutions of these finite differential equations have been obtained by the relaxation method. And also. the local and average Sherwood numbers have been calculated from above solutions.
Flow pattern visualized by tracer has been considerably similar to calculated one. The calculated values of average Sherwood number under various Schmidt and Reynolds numbers have been consistent with experimental ones obtained in the previous paper. An example of the absorption rate of nitrogen into liquid iron has been shown for the case in which the rate of absorption is controlled by mass transfer in gas phase.
