A METHOD OF SUPPRESSING CONVECTION IN A FLUID IN A CYLINDRICAL VESSEL

摘要

An object of the present invention is to provide a method of suppressing convection of a fluid in a cylindrical vessel by means of realizing an environment under micro gravity which can be maintained for such a long time that growth of a large-sized crystal be economically effected. The feature of the present invention consists in a method of suppressing occurrence of natural convection of a fluid in a cylindrical vessel, when a density gradient due to difference in temperature, concentration or partia l pressure is added to the gas or liquid filled in the cylindrical vessel alon g the central axis of the vessel, characterized by maintaining horizontal the vessel and rotating it around the central axis.
