Analysis of Relations for Calculating Normal Heat Transfer to Supercritical Pressure Water Flow in Vertical Tubes

Abstract

The generalized relations for calculating the coefficient of normal heat transfer during forced motion of water at supercritical pressure in vertical tubes is analyzed. It is shown on the basis of a comparison with a large experimental database (more than 4000 experimental points from 20 domestic and foreign works) that the equation obtained by the present authors gives the best agreement between the computational and experimental results for regimes with normal heat transfer in water near the critical point.
