The wall film-wise condensation plays an important role in the heat transfer processes of heat exchangers, refrigerators, and air conditioner. In the field of nuclear engineering, steam condensation isoften utilized in safety systems to remove the core decay heat under both transient and accident conditions. In particular, passive containment cooling system (PCCS), are designed to ensure containmentsafety under severe accident conditions. A computational fluid dynamics (CFD) scale analysis has beenconducted to calculate the heat transfer rate of the PCCS. However, despite the increase in computingpower, there are challenges in the long-term transient simulation of containment using CFD scale codes.
In this study, a heat structure coupling between the CFD and system analysis codes was performed toefficiently analyze PCCS. In addition, the component unstructured program for interfacial dynamics(CUPID) was improved to analyze the condensation behavior of ternary gas mixtures. Thereafter, thecondensation heat transfer on the primary side was calculated using the improved CUPID and CFD code,whereas that on the secondary side was simulated using MARS. Both the coupled codes were validatedagainst the CONAN facility database. Finally, conjugate heat transfer simulations with wall condensationin the presence of non-condensable gases were appropriately performed
