Applications of a (k-epsilon) model for the analysis of continuous castingprocesses.

The finite element solution of the turbulent Navier-Stokes equations develo ped via (k-epsilon) turbulence models was addressed in previous publication s [1-4], where a (k-L)-predictor/(epsilon)-corrector-iterative algorithm wa s developed. It was shown that the developed algorithm is robust and conver ges for the analyses of different flows without requiring the implementatio n of ad hoc numerical procedures. The turbulent convection-diffusion transp ort equations are solved by using the velocity distributions determined fro m the solution of the turbulent Navier-Stokes equations. The dispersion of a die in a turbulent flow can therefore be modelled and the obtained disper sion patterns are validated via flow visualizations in water models. In the present paper, the developed analysis capability is applied to the analysi s of continuous casting processes. Copyright (C) 1999 John Wiley & Sons, Lt d.
