## Experiments Ire reported for condensation of steam on horizontal grooved tubes of 1.9 cm diameter with 14.2 grooves/cm (36 tpi Standard American Screw Thread). Three tube wall materials were used: copper. brass and 70-30 cupronickel. The effect of noncondensable gas was investigated'for steam-a

Film condensation of stagnant water vapor on both vertical and horizontal spir~ly fluted robes was studied theoretically. A sine flute was taken as a typical example. In the analysis two regions of the flute, namely the valley and the crest, are treated separately. The condensation process takes pla
A numerical study of steam condensation over horizontal fluted tubes is presented. Condensate is driven by surface tension to the groove valley where it is drained by gravity. From the bottom to the top the groove domain is divided into a valley section, crest section with large variations of cond
