Abstract

Verified numerical simulation of heat transfer through the structure is an effective tool that allows to shorten development time and reduce development costs. The thesis describes numerical simulation of heat transfer in a heating unit structure for sapphire single-crystal growth. Heat transfer through radiation and conduction was simulated using commercial FEM software. As time dependent simulation requires high computing capacity, the 3D model has been simplified. The calculated temperature values are compared with the measured temperatures during the crystal growth process. This analysis is aimed at assisting in the construction design of similar heating units or in optimization of the current heating unit.
