摘要

The results of analysis to develop an advanced computer model, STEAMFREQ-I, for the investigation of density-wave instabilities in steam generators with imposed heat flux are presented. The key model features include a drift flux flow model in the boiling region, spatial variation of heat flux, wall dynamics, and variable steam properties in the superheat region. Stability predictions for STEAMFREQ-I are compared with those from two other codes. In addition, stability predictions are compared with data representing unstable and stable conditions obtained from a solar receiver panel test and with stability threshold data from a sodium-heated steam generator test.
