Flow Stability in Heat Transfer Matrices under Boiling Conditions

摘要

The stability of fluid flow for cases in which boiling occurs in parallel passages has posed questions of design feasibility recently in several areas including once-through steam generators for large gas-cooled reactors, water-cooled reactors such as the MTR, and small compact reactors cooled by a boiling alkali metal. A survey of the literature has disclosed a number of treatments of the subject, but there appears to be no comprehensive presentation that makes it easy for the designer to envision the regions under which stable flow conditions would prevail. It appears possible to cover most of the conditions of interest with a few charts which have been prepared to provide the necessary information for the designer.
