Abstract

The results of the CFD modeling of heat transfer under condition of the upstream flow of supercritical water in vertical bare tubes are presented with a change in the wide range of mass flux and heat flux at the channel wall. The results of comparison of experimental and calculated data for different heat transfer regimes - improved, normal and deteriorated - are presented. The results of the CFD modeling relating to the spatial distribution of physical properties of supercritical water are analyzed.
