摘要

A condensation experiment in the presence of non- condensable gas in a vertical tube of the passive con- tainment cooling system of the CP-1300 is performed. The experimental results show that the heat transfer co- Efficients (HTCs) increase as the inlet air mass fraction Decreases and the inlet saturated steam temperature de- Creases. However, the dependence of the inlet mixture Reynolds number on the HTC is small for the operating Range. An empirical correlation is developed, and its Predictions are compared with experimental data to show Good agreement with the standard deviation of 22.3/100.
