Investigation of transient fluid flow and heat transfer in a continuous casting tundish by numerical analysis verified with nonisothermal water model experiments

摘要

The tundish process is complicated due to theperiodic nature of its operation during the changing of ladles,which makes it both a transient and nonisothermal process. Anonisothermal water model, with temperature variations in the inletstream, is described in this article. A three-dimensional (3-D)transient mathematical model to simulate the fluid flow and heattransfer in this water model is also introduced. From theexperimental and numerical results, it is shown that there is asignificant thermal buoyancy force contributing to the flow in thisnonisothermal water model.
