Abstract
In the present study effect of steam temperature on heat transfer coefficient is studied using ANSYS Fluent (2015). In this study CFD analysis is performed to validate experimental data of condensation heat transfer coefficient. Steam temperature is varied from1030C -1150C and its effect on heat transfer coefficient is done. Three helical coils having different coil diameter is used. Steam is flowing inside the tube and water is flowing through the shell. It is observed that as saturation temperature of steam increases heat transfer coefficient increases and as coil diameter increases heat transfer coefficient decreases and the percentage of error is within 9-15%.In addition with this impact of variation in tube diameter on heat transfer coefficient is studied and it is observed that as tube diameter increases heat transfer coefficient increases.
