Abstract : A two-phase Eulerian solver has been modeled to compute the effect of condensation heat transfer coefficient on laminar film condensation. For analysis, the solver is incorporated with void fraction, energy equations for individual phases and a set of empirical correlations to compute average heat transfer coefficient, film thickness and the amount of condensate formed. A Finite Volume Method (FVM) is used to discretize the governing equations. At a constant flow rate, the effect of film thickness and mass of condensate formed over vertical surfaces with varying temperature differences (T) are studied. The result indicated that the heat transfer coefficient tends to decrease with an increase in film thickness.
