Two-dimensional numerical simulation for experiment of wall condensation from steam-air mixture along a flat plate was carried out with GOTHIC, which is a general purpose thermal-hydraulics analysis code. The characteristics of GOTHIC code were investigated by changing cell size near the condensation surface, and comparing the heat transfer coefficient and other parameters with experimental data. In the case where the cell size was y⁺ = 1, difference in the analysis results was larger than that in other cases, and in the case where y⁺ > 6, the analysis results were stable.
