ABSTRACT

A problem of convective heat and mass transfer for a two-dimensional cylindrical domain φ is a symmetrical model of the Bridgeman ampoule) is considered on the basis of system of nonstationary Navier—Stokes equations. A numerical algorithm is developed and computations of the Grasgof number G_R — 5 × 10⁵ for a short and a long cylinders were done. An effect of vertical drift of vortical flow and of isotherms under the absence of the radial temperature gradient in cylinder was revealed.
