Description of a New Tundish Model for Treating RTD Data and Discussion of the Communication “New Insight into Combined Model and Revised Model for RTD Curves in a Multi-strand Tundish” by Lei

A new tundish model was proposed for analyzing data of the residence time distributions. It was based on an approximated analytical solution for the model of Sahai and Ahuja,[1] which is described elsewhere.[2] Subsequently, it was applied along with some analytical results for well-mixed tanks in a comprehensive discussion of Lei’s work.[3] This discussion contributed to a better understanding of the RTD theory applied to the analysis of fluid flow in continuous casting tundishes.

Consider a one-strand tundish of volume \( V \)
