TL;DRAbstract

It is a well-known fact that in the Czochralski crystal growth, as well as in all other crystal growth processes from the liquid phase, the flow in the melt has a strong influence on the chemical and physical properties of the growing crystal. Unlike some other techniques the Czochralski crystal growth technique, with the view to itsdynamics, represents a rotating systerm,which is rich in many flow phenomena not existing in non-rotating systems. For this reason, some notion of the theory of rotating fluids will be necessary for better understanding of fluid dynamics in the Czochralski crystal growth. This report consists of two parts. In the first part, elements of the theory of rotating fluids are given. It covers, among others, such topics as Taylor-Proudman theorem and its consequences on the fluid flow; Ekman boundary layer; forced oscillations in a rotating fluid which might influence the crystal growth in those cases in which both,the crystal and the crucible, are rotated and the
