Numerical Simulation of Condensation on a Capillary Grooved Structure

Condensation in a capillary groove is investigated using the volume of uid ( VOF) model. The governing equat ions are written in a generalized form and are applicable to both liquid and vapor phases. Condensation on the n top and at the meniscus is modeled by intro-ducing addit ional source terms in the cont inuity, VOF, and energy equations. The effects of temperature drop, contact angle, surface tension, and n thickness on the condensation heat transfer are also investigated
