Segregation Phenomena in Phase Transition in Multicomponent Media in Microgravity

Segregation phenomena are widely used in many material production field of industry. From the mathematical point of view segregation can be described by additional nonlinear substance source on the phase transition boundary. In dependence on specific feature of phase transformation process there can be two kinds of segregation boundary conditions, but in any case the source is proportional to segregating substance concentration. The slow phase transition case in multicomponent media is considered in the present work. Combined small parameter and boundary element method proposed in previous work by the authors is applied to the phase transition calculation. This approach is generalized on the case of multicomponent media. The proposed algorithm is illustrated by several examples of numerical calculations.
