Numerical investigation of heat and mass transfer processes accompanying crystallization under conditions when body forces produce weak accelerations

A numerical investigation has been made into the development of the flow of a liquid and distribution of an dopant during crystallization under conditions when weak body forces act. It is shown that the development and structure of the flow, and also the distribution of the dopant over the height of the liquid volume and along the radius near the crystallization boundary are influenced by the thermal boundary conditions and the wettability of the ampoule wall by the liquid. The mean (over the height of the ampoule) radial inhomogeneity of the dopant distribution is found as a function of the time and the regime parameters (the Grashof, Marangoni, and Schmidt numbers).Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 186–192, January–February, 1981.
