Numerical simulation of turbulent bubbling flow induced by gas jet into metal melt

Numerical simulations of the flow processes of gas jet into metal melt were conducted by using the Eulerian-Eulerian two-fluid approach. A two-phase version of the k-Ε turbulence model was used for the liquid and gas (bubbles) respectively. Effects of the inter-phase momentum exchange were examined with the emphasis on the influence of drag and lift forces. Agreements between computational results and the experimental data from the literature were obtained by properly turning the drag and lift coefficients. There are still some discrepancies near the gas nozzle, which can be attributed to the lacking of a jet breakup model.
