The purpose of this study is to find out influence of wettability on condensate film behavior. We used two material balls, Alumina Ball (AB) and Coated Alumina Ball (CAB). CAB have higher wettability than AB. This study was conducted by streaming the humidity-air over the porous media surface in a chamber covered by ambient-air. Condensation film behavior in the system was visualized by use of video camera. The main result mention that condensate film behavior of AB media was channel flow, whereas its of CAB media was almost drop wise condensation under low humidity-air temperature.
