Abstract

Abstract

A numerical method is developed to predict the steady-state and transient behaviors of forced-convection flow in steam generator.From the basic differential conservation equations,an intact model is constructed fully considering the structure of the steam generator,its possible flow and heat transfer.Gear method is adopted,The curves of flow instabilities and unstable regions are acquired with computation.The effects of pressure,flow flux,inlet subcooling and inlet/outlet throttle on the system behaviour are discussed.
