| Abstract: | A mathematical model of flow characterization in multi-strand continuous casting tundishes was attempted to put forward, the standard of plotting residual time distribution (RTD) curves was definitely presented and a relative calculation method was proposed. The feature of dead region was carefully studied and a method to calculate its volume fraction was given in the model. What's more, the model considers bypass flow and proposes a method to calculate its volume fraction. Experimental results show that th... |
