A model is developed to predict the shape of a drop or condensate bridge by numerically solving the Young-Laplace equation which governs the shape of the liquid-vapor interface, subject to a prescribed shape of the base contour and variation of the contact angle along the base contour. The model is successful in predicting the shapes and volumes of condensate elements on surfaces with widely varying hydrophilicity. In addition to its utility in predicting the volume (or mass) of condensate retained on fin surfaces as drops or bridges, this model can be used to study the effects of hydrophilicity on inter-fin or inter-louver condensate bridging.
