| Abstract: | The condensation heat transfer of gasoline-air mixture gas(the range of non-condensable gas mass quantity is 2%-13%) in horizontal tube was carried out.Condensation heat transfer characteristics is investigated for a horizontal tube with non-condensable gas.Condensation heat transfer coefficient could be predicted by Re and Co of liquid film.The correlation of condensation heat transfer coefficient was established. |
