The present study has been carried out to increase the understanding of the phenomenon of condensation heat transfer at the steam-water interface in countercurrent stratified horizontal pipe that has a length of 2m and inner diameter of 83mm.The method of measuring the increase of the bulk temperature in the water flow layer and then deducing the interfacial condensation heat transfer coefficient has been used to obtain the information of the thermal resistance of the water flow. In the present experiments the water layer was thick enough for the thermal stratification to be established, and that increased the thermal resistance of the water layer to the condensation heat transfer significantly. As a result, the interfacial condensation heat transfer coefficient becomes very small. In the present study, two types of correlations that can predict the interfacial condensation heat transfer coefficient in the countercurrent stratified horizontal pipe flow were developed.It is shown here that the correlation involving interfacial turbulence property gives a better agreement with the present experimental data than the correlation involving bulk flow properties.
