## Abstract This paper deals with investigation of the behavior of the profile curves of the melt menisci for the case of the sapphire crystal growth by EFG (Stepanov) technique. The cases of external and internal circular menisci of the crystal tube are considered. The cases of the positive and ne
## Abstract Profile curves of the small liquid menisci are investigated on the base of numerical solution of the Young – Laplace equation. There are considered menisci for the growth of crystal capillaries and fibers by the EFG (Stepanov) technique. Differences in the shapes of the small and “large
## Abstract 3D simulations using the commercial CFDRC and FIDAP code, which are based on finite element techniques, were performed to investigate the effects of anisotropic conductivity on the convexity of the melt–crystal interface and the hot spots of sapphire crystal in a heat‐exchanger‐method c
