Abstract

Influence of turbulent natural convection in simulating crystallization of II-VI semiconductors P. Jelmek\ R. Cernyi & P. Pfikryl^ * Department of Structural Mechanics, Faculty of Civil Engineering, Czech Technical University, Prague 6, Czech Republic ^Mathematical Institute of the Academy of Sciences of the Czech Republic, Prague 1, Czech Republic Abstract A theoretical model of binary alloy solidification is formulated using the mass, momentum and energy balances in the liquid and the mass and en- ergy balances in the solid. The turbulent energy and momentum transfer are taken into account using two different turbulent k — e models for low Reynolds numbers. The interface between the solid and liquid phases is modeled as a discontinuity surface where the mass, momentum and energy balance conditions are expressed. The linear theory of mixtures is employed in modeling the two-component system. In a practical application of the computational model, the crystallization pr
