Condensation occurs when the steam contacts the surface and cools to a state below the saturation temperature. To understand the relationship between the surface energy and the change of the condensate behavior, it is necessary to understand the adhesion force. Many researchers used the line contact analysis method to predict the adherence of droplets. However, it is difficult to apply the line contact analysis method to surfaces with different surface energy. To solve this problem, a new model was proposed in the recently study to predict the adhesion of droplets using surface area. The new model showed better adhesion predictions on flat surfaces compared to the models developed in previous studies. In this study, the adhesion of droplets in the micro structured surface is analyzed. Moreover, the adhesion force model using the line contact model and the contact area is compared.
