To study the effects of the gas channel wall contact angle on the behavior of a liquid water slug, numerical simulations are performed with the volume of fluid (VOF) method. Two different contact angle combinations on the side and top channel walls are selected. In comparison to the reference case, the water slug is removed faster when the hydrophobic contact angle is applied selectively in the corner section.
