Abstract |
Condensation occurs when steam contacts a cool surface and attains a temperature below the saturation temperature. To understand the relationship between the surface energy and the change in the condensate behavior, it is necessary to understand the adhesive force. A host of researchers have employed the line contact analysis method to predict the adherence of droplets. However, it is difficult to apply this method to surfaces possesing different surface energy. To solve this challenge, recent studies have proposed a new model to predict droplets adhesion using surface area. The new model exhibited better adhesion predictions on flat surfaces compared to the earlier models developed from previous studies. In this study, the adhesion of droplets in the micro structured surface was analyzed. Moreover, the adhesion force model using the line contact model and the contact area was compared. |
