Abstract: An experimental study was made for steam condensation in a vertical tube with a spiral wire based on the turbulent-turbulen heat transfer model of steam-1iquid f1ow proposed by the authors,and data correlation was obtained.The distribution of steam content along flow length was calculated ad the influences of spiral wire,steam velocity,steam pressure and codensate film on condensation were analysed.The enhancement of condensation by the spiral wire was also demonstrated.
