A. O. Gusev, O. S. Mazhorova


Abstract: The structures of axisymmetric flows formed in a rotating cylinder are studied. The upper boundary of the cylinder consists of a rotating disk and a free surface. The physical and geometrical parameters of the system under consideration align with advanced stage of Czochralski single-crystal growth. The influence of natural and forced convection on heat transfer within the system is investigated. The fully conservative numerical scheme which ensures the validity of momentum, kinetic, and internal energy balances is employed in computations.

Keywords: natural convection, forced convection, rotating fluid, Czochralski crystal growth, numerical simulation.
