Abstract

Data relating to flow and heat transfer features of the supercritical water in bare tubes at varying of values of heat flux density supplied to the tube wall and inlet pressure are obtained based on CFD-simulation . The results of the analysis of the effect of these values on the basic heat-hydraulic parameters of supercritical water are presented.
