Single-Tube Thermal and Hydraulic Tube Support Test Volume 1

摘要

The work described in this report (volumes 1 and 2) was an experimental project to measure the inception and extent of dryout or liquid deficient heat transfer and chemical precipitation in presently used steam generator tube-tube support geometries and modified geometries. Since chemical precipitation or concentration may lead to corrosion this program was planned to find the dependence of dryout and chemical precipitation on geometry, heat flux and fluid conditions. The interrelation¬ship between the heat and mass transfer processes in the crevices was further demonstrated by comparing the results of an analytic model for predicting the shape of the liquid vapor interface to the outline of a precipitate pattern resulting from chemical concentration.
