Mathematical relationships of models of two-phase flows in channels of reactors and steam generators of NPP's for the calculation of their hydrodynamic characteristics

Two-phase flows of the working substance in the steam-generating channels of reactors of single-circuit NPP’s and steam generators of two- and three-circuit NPP’s represent the joint movement of liquid (feed water) and steam in the form of a steam-water mixture. The forms of movement of two-phase fl...
