STABILITY ANALYSIS OF HEATED FLOW CHANNELS WITH SUPERCRITICAL WATER

摘要：

The thermal-hydraulic stability of uniformly heated channels under supercritical water conditions have been investigated to understand the phenomena of density-wave-oscillation (DWO) which may occur in Supercritical Water Nuclear Reactors (SCWR). We have extended to supercritical pressure operation conditions the modelling approach often used for 2- phase-system linear stability analysis. The stability of heated channels was computed by evaluating the eigenvalues and eigenfunction of the model. We have found a strong influence of the state equation on the results. We have investigated the neutral stability boundary of two coupled identical channels with a common inlet orifice.
