Heat-transfer coefficients for film condensation of steam on an inclined cylinder

This thesis discusses an investigation of film condensation of steam on the outside surface of an inclined cylinder. The objectives of the investigation were (1) to obtain heat-transfer coefficients for steam condensing on an inclined cylinder, (2) to determine the effect of the angle of inclination of the cylinder on the condensing coefficient, and (3) to verify values of the coefficient obtained from an accompanying theoretical development.
Experiments were conducted for steam condensing on a 12.45 in. length of the outside surface of a 3/4 in. diameter by 0.065 in. thick wall, water-cooled, copper tube.
Condensing coefficients were obtained for inclinations to the horizontal from 0° to 90° at 15° intervals. It was found that these coefficients decreased in value as the angle of inclination increased from 0° to 90°. At the same time good agreement was obtained between the measured and theoretical coefficients. No single equation could be found which would correlate the results for all the inclinations tested, but general equations were obtained which apply for each of two zones. One zone included inclinations from 0° to 30°, the other inclinations from 45° to 90°. The zone from 30° to 45° requires more investigation before it can be satisfactorily correlated. / Applied Science, Faculty of / Mechanical Engineering, Department of / Graduate
