Simulation of physicochemical processes of erosion-corrosion of metals in two-phase flows

A computational model for erosion-corrosion of the metals of the power equipment in two-phase flows (RAMEK-2) was developed. The results of calculations of the dependency of the intensity of the erosion-corrosion of structural steels as a function of the thermodynamic, hydrodynamic, and water-chemistry parameters of these flows in the working paths of TPSs and NPSs are presented in three-dimensional space. On the basis of mathematical models, application software was created for forecasting the erosion-corrosion resource and for optimizing the rules on diagnosing and protective maintenance of erosion-corrosion of the elements of the wet-steam path in power stations.
