Axisymmetric calculations of inert gas flow in a floating zone puller are carried out using an
open source software package OpenFOAM. Transient axisymmetric melt flow in liquid silicon
and quasi-stationary shape of silicon phase boundaries are calculated using a specialized
program FZone. Additional heat losses at silicon surfaces caused by the gas flow are taken
into account for argon and helium, while maintaining the height of molten zone by adjusting
inductor current. Cooling causes an increase of electromagnetic force, heat sources and …
