| dc.description.abstract | This paper presents the results of research on temperature profiles on multi-location of condensation of steam flow
cooled using parallel flowing water in an outside of a horizontal pipe. The test section consisted of a copper pipe
(din= 17.2 mm, do= 19 mm, 1.8 m long) as inner annulus and a galvanized iron pipe (din = 108.3 mm, do = 114. 3 mm,
1.6 m long) as outer annulus. The experiments were conducted at a static pressure (Ps) of 109 kPa. The fluid is water
in two phases i.e. steam and liquid. The steam phase flowed inside the inner pipe, while as the cooler, the liquid
flowed through the annulus. The flow of steam was then cooled using parallel flowing water in the outside of a
horizontal pipe. Data acquisition equipment was used to record data at a sampling rate of 5 Hz. The results showed
that a point farther away from the inlet tends to have a lower temperature. The increase of steam mass flow rate
(mst) resulted in the larger instability and started to generate wavy slug flow. Therefore, the wavy-slug flow pattern
occurred close to the outlet of the pipe | en_US |
