Abstract
New heat-transfer measurements are reported for condensation of refrigerant 113 and ethylene glycol (ethanediol) on a single horizontal tube with vertical vapour downflow. For refrigerant 113 tests were carried out at atmospheric and sub-atmospheric pressures. Vapour velocities up to about 9 m/s were obtained. For ethylene glycol measurements were made at several pressures ranging from around 2 kPa to around 18 kPa. A few data points were obtained at pressures as low as 0.2 kPa. For ethylene glycol the range of vapour velocity was approximately 2 − 120 m/s. Implications of the results for the condensation mechanism are discussed.
