“…In particular, with the development of seawater desalination and the nuclear power industry, the condensation heat transfer with a non-condensable gas is becoming a research focus. Earlier results studied few possibly trace amounts, of non-condensable gases [4,8] , geometries [16][17][18][19][20][21][26][27][28] , and flow patterns [6,29] , while only a few experiments involved the condensation heat transfer process with a high fractional non-condensable gas [7,15,[30][31][32][33][34] . The general trend the research follows is: attaining a more reasonable experimental system design, and then increased reliability of the measurement of variable parameters, especially the temperature of the condensing plate, temperature of the bulk vapor mixture, and gas-liquid interface temperature.…”

The effect of a non-condensable gas on steam condensation has been studied. From experimental and theoretical studies to date, clear evidence of significant heat transfer deterioration by the non-condensable gas can be seen. The deterioration varies with the concentration of the non-condensable gas, geometric parameters, system pressure, etc. However, these data and correlations may be unreliable due to the high concentration of CO 2 in the vapor mixture and lack of verification through experiments. In this paper, a systematic investigation has been conducted for film-wise condensation using a vapor mixture of steam and a high concentration of CO 2 . Some data were obtained on a vertical plate, with the average vapor velocity of 1.2 m/s, CO 2 mass fraction of 20%-94% and a pressure of 1 atm. The effects of CO 2 concentration and surface sub-cooling on heat transfer characteristics have been investigated. Moreover, the relevant parameters such as gas/liquid film resistance were included in the description of the condensation phenomenon. The developed correlation for steam and a high concentration of CO 2 , based on experimental results, has a standard deviation of less than ±20%.
