The heat transfer of steam condensation in an inclined tube with relatively large diameter was experimentally investigated.Moreover

the test data were analyzed to obtain a suitable experimental correlation.The results showed that

the deviations of heat transfer coefficients between the experimental data and the calculation results according to correlations such as Shah correlation

Würfel correlation and Akhavan-Behabadi correlation were all larger than 30%

while among which the error between the test data and calculation results by the Akhavan-Behabadi correlation was the lowest.On the basis of the Akhavan-Behabadi correlation

a new correlation was presented and applied to condensation heat transfer calculation in an inclined tube with relatively large diameter.Results showed this new correlation was more accurate

of which the heat transfer error was less than 15%.
