Ebook: Impurity distribution in submerged heating method with and without rotation

Proc. Int. Conf. on Computational Heat and Mass Transfer. April 26-29, pp. 207-215, N. Cyprus, Turkey, 1999.Results of unsteady 2D Navier-Stokes mathematical modeling of convection-diffusion processes are presented. The equations are solved by finite element method in the cylindrical region. Taking into account a calculated history of dopant concentration at the surface of the crystallization we determine a distribution of the dopant concentration in crystal. An influence of steady and oscillatory rotation of submerged heater on distribution of dopant in crystals is investigated.
