We carried out analyses for existing COPAIN and CONAN experiments by using the CFD code FLUENT and the computation model for condensation heat transfer from steam-air mixture on a vertical flat plate made in our previous study, and compared the computed heat fluxes with the measured heat fluxes. The computed heat fluxes were smaller than the measured ones in the region of small x (where x is distance from the entrance), and it was significant for the CONAN analyses. The computed heat fluxes agreed with the measured ones within measurement uncertainty except the region of small x.
