✦ Synopsis

The "nite element solution of the turbulent Navier}Stokes equations developed via (k} ) turbulence models was addressed in previous publications [1}4], where a (k}¸)-predictor/( )-corrector iterative algorithm was developed. It was shown that the developed algorithm is robust and converges for the analyses of di!erent #ows without requiring the implementation of ad hoc numerical procedures. The turbulent convec-tion}di!usion transport equations are solved by using the velocity distributions determined from the solution of the turbulent Navier}Stokes equations. The dispersion of a die in a turbulent #ow can therefore be modelled and the obtained dispersion patterns are validated via #ow visualizations in water models. In the present paper, the developed analysis capability is applied to the analysis of continuous casting processes.
