Description

This paper presents the results of an experimental investigation of enthalpy migration in a horizontal test assembly with two interconnected subchannels. Measurements were conducted using water at pressure and mass flux typical of CANDU reactor conditions. For mass fluxes at and below 4 Mg/M2s, the upper subchannel carried considerably more energy than the lower one. At the highest mass flux of 5 Mg/m2s, the enthalpy migration phenomenon seemed to disappear. A comparison was made between the ASSERT code predictions and the test data at several mass fluxes and, under flow matching conditions, good agreement was found. (Author) 7 refs., 7 figs., tab
