A two-dimensional model of heat and mass transfer in the 
process of fractional crystallization on a band is proposed. Algorithms 
for calculating the concentration of an impurity in a melt have been 
developed and the impurity distributions in a diffusion layer have 
been obtained for the cases of linear-profile and wavy-profile crystals 
on the basis of numerical experiments. It has been established that 
the impurity distribution is two-dimensional in the case of a wavy-profile 
crystal.
