Abstract

The formulation of the problem, the numerical solution method, and description of the test calculation case for modeling a melt flow in the problem of crystal growth by the Czochralski (Chochralsky) method are presented. The mathematical model is based on regularized or quasi-hydrodynamic (QHD) equations to describe a viscous, incompressible heat-conducting fluid. The numerical algorithm is implemented on the OpenFOAM package within the mulesQHDFoam solver. The proposed approach allows calculations of an unsteady three-dimensional flow in a crucible with the given geometry for high Reynolds and Grashof numbers. As an example, the results for the flow in a simplified configuration are given. An asymmetric transient flow is obtained.
