The subject of this study was a correlation for wall condensation heat transfer which is used as boundary conditions on structure surfaces in computational fluid dynamics (CFD) analysis for thermal hydraulic behavior in a containment vessel (CV) during accident conditions. In this report, we carried out numerical analysis for COPAIN experiments for condensation heat transfer from steam and air mixture on a vertical flat plate by using the CFD code, FLUENT, and we confirmed that the measured heat fluxes for natural convection condensation were relatively well simulated by the CFD analysis.
