Erratum to: A Mathematical Modeling Study of Tracer Mixing in a Continuous Casting Tundish

Abstract

Specifically, in the transport equations for the mass fraction of water, tracer, and the scalar (Eqs. [7], [8], and [13], respectively). The density properties were the density of the mixture in Eq. [10] instead of the density of the water or the tracer itself. Second, the update of one of the result in the article. Regarding the result (1) KCl density only (OD) in Table II and the text in p. 179: ‘‘Apart from the KCl molecule diffusion, the mesh difference could also, to some extent, influence the differences in the results.’’ The result (1) KCl density only (OD) was based on a mesh of 168 9 71 9 70 grids, while the other results (2) through (5) were based on a mesh of 193 9 79 9 117 grids. A new simulation for the (1) KCl density only (OD) were recently made based on a mesh of 193 9 79 9 117 grids to maintain the consistency. It was difficult to distinguish the difference between the RTD curves of the case that implemented with density only (OD) and the case implemented with both density and KCl molecule diffusion (KMD). To conclude, all the properties of tracer (except for the density) that implemented in the CFD model could not affect the calculated RTD curves.
