Abstract
Combined model in which a tundish is divided into plug flow, well‐mixed flow, and dead region has been widely used for the analysis of residence time distribution curve in an actual tundish. However, the calculation of dead volume in conventional or Sahai's method does not follow its definition in the model assumption, which probably results in incorrect conclusions for flow field optimization of tundish. In this study, two methods for dead volume calculation are discussed, the well‐mixed volume is further divided into equivalent, active, and dead well‐mixed volume. Therefore, the method for dead volume calculation is revised by eliminating the contribution of dead well‐mixed flow. Water modeling experiments of single and multi‐strand tundish are conducted. The new calculation method is applied to analyze the residence time distribution curves and calculate the dead volume fraction in comparison with the other two methods. The results show after the dead well‐mixed flow is eliminated, the dead volume fraction calculated by the new method is smaller than those calculated by conventional and Sahai's method. According to the flow visualization experiments, the dead volume fraction calculated by the new method in this study is more rational than those calculated by the other two methods.
