Abstract
Designed mathematic model allows calculating trajectories of spherical non-deformable particles movement in the flow of viscous non-burnt liquid in the flat canal of complex geometry. According to the results of calculations graphs of dependence of precipitating particles share on their diameter and degree of curvature of the researched canal have been built.

Summary
Economical efficiency and reliability of turbines work operating in the area below the curve of saturation mostly depends on moisture of vapor. The present work considers movement of two phase area consisting of non-burnt liquid and discrete phase in the form of separate spherical drops. The purpose of the work is mathematic modeling of movement of drop moisture in the canal with set geometry and study of the process of precipitating at different canal curvature.
