Hydrodynamics of gas-liquid annular dispersed flows in rod bundles

One-dimensional stationary hydrodynamic model of gas-liquid mixture flow in the disperse-film regime in channels with rod bundles has been constructed on the basis of representations on gas- liquid disperse-annular flows in round tubes within the framework of a cell flow model. Mass and strength interactions between the components of the disperse-film flow within and between the cells are analysed. Dependences of basic hydrodynamic characteristics of steam-water disperse-film flow in the section and in channel length on regime mixture parameters have been shown. Carried out comparison of experimental and calculated characteristics of disperse-film flows in the channel with rod bundles of different geometry shows that the developed model describes adequately basic hydrodynamic characteristics of such flows
