摘      要：Fluid flow and mixing of molten steel in a twin-slab-strand continuous casting tundish were investigated using a mixing model under non-isothermal *** model led to a set of ordinary differential equations that were solved with a Runge-Kutta *** state water modeling was carried out under non-isothermal *** data obtained from the water model were used to calibrate the mixing *** to the presence of a mixed convection in the non-isothermal conditions,a channelizing flow would be created in the fluid inside the tundish.A mixing model was designed that was capable of predicting RTD（residence time distribution）curves for different cases in non-isothermal *** relationship between RTD parameters and the Tu（tundish Richardson number）was obtained for various cases under non-isothermal *** results show that the RTD parameters were completely different under isothermal and non-isothermal *** comparison of the RTD curves between the isothermal and non-isothermal conditions presents that the extent of mixing in the tundish in non-isothermal conditions is lower than the mixing extent in isothermal conditions.
