Development of Heat Transfer Models for Horizontal Heat Exchanger of Passive Containment Cooling System (PCCS)

Abstract

A series of fundamental heat transfer tests using a horizontal U-shaped condenser tube were performed to estimate the characteristics of a horizontal heat exchanger for a passive containment cooling system (PCCS). This paper summarizes new correlations to predict non-condensable gas effects on heat transfer and annular condensation heat transfer taking the roll-wave stirring effect into consideration.
