FEATURES OF SPATIAL DISTRIBUTION OF THE SPECIFIC HEAT CAPACITY OF SUPERCRITICAL WATER DURING ITS FLOW IN VERTICAL BARE TUBES

Abstract

The results of computer modeling of the spatial distribution of the specific heat capacity under condition of the upstream flow of supercritical water in vertical bare tubes are given. The features of the motion along the tube length the front of the pseudo-phase transition "pseudoliquid-pseudogas" are considered. The position of this front determines the location of the extremums of the specific heat capacity of water. The regularities of changes in the radial distributions of heat capacity along the length of the tube and longitudinal distributions for different values of the radial coordinate are investigated. The data of a comparative analysis of this distribution at various values of the specific heat flux supplied to the tube wall are presented
