EXPERIMENTAL INVESTIGATION ON THE LOCAL PROFILES OF HEAT TRANSFER COEFFICIENT DURING THE STEAM CONDENSATIION IN A HORIZONTAL ANNULUS PIPE
Abstract
The objective of the research is to investigate the heat transfer profiles by using a
measurement of the temperature distributions during condensation in a horizontal annulus pipe.
The circumferential temperature distribution along the annulus pipe wall were measured in
order to investigate the heat transfer characteristics around the annulus pipe. An annulus pipe
with inner section test pipe made from copper material (din = 17.2mm, do = 19mm) with a
length of 1.8m and outer section test pipe made from a Galvanized Iron Pipe (din = 108.3mm, do
= 114.3mm) with a length of 1.6m covered by 10 mm thick insulation was used in this experiment.
