Abstract

The results of computer modeling of heat exchange supercritical water, associated with the influence of gravity, are presented. CFD prediction data on heat transfer coefficients and temperatures of the inside surface of the tube wall, obtained with and without buoyancy, are presented. An interpretation of these predictions, which is associated with the turbulent transfer extinction near the tube wall in the case of buoyancy forces, is given. The analysis of the influence of buoyancy forces on the configuration of the radial temperature profiles of supercritical water was performed. The data on the regularities of motion of the pseudo-phase transition front in the presence and absence of accounting for buoyancy forces have been obtained.
