摘要：

An Eulerian-Lagrangian computational model for simulations of gas-liquid flows in a continuous casting mold is developed. The flow of the fluid phase is solved in an Eulerian frame of reference together with the motion of every individually injected gas bubble, solved in its own Lagrangian frame of reference. It is assumed that the gas bubbles remain spherical and their shape variations are neglected. In order to consider the bidirectional interactions between the bubbles and the melt flow two different methods (the one-way coupling and the two-way coupling) are studied and compared. The simulations show that the two-way coupling is essential to get realistic results.
