Abstract
We report on an experimental study of high-pressure (up to 65 bar) steam condensation heat transfer in a slightly inclined tube at the thermal-hydraulic test facility COSMEA. The study is part of an extended experimental program on this topic and focussed this time on heat transfer and two-phase flow at low inlet steam qualities (down to 2.8%). We determined condensation rates respectively total heat transfer, wall heat flux distribution and flow morphology using X-ray imaging and local temperature measurements.
