Hello,<\/p>\n

<\/p>\n

I am modeling a 2d multiphase flow (air and water) with gravity enabled in negative x- and y-direction. It seems that the water flows along the wall, even though the gravity is greater in y-direction (see below). The area is filled with air. Did I forget to disable any kind of wall adhesion? If I increase my velocity at the inlet, it doesn’t flow along the wall.<\/p>\n

<\/p>\n

Some Boundary Conditions:<\/p>\n

<\/p>\n

   Gravity: x: -4.25 m\/s² ,      y: -7.3575 m\/s²<\/p>\n

<\/p>\n

   Velocity at inlet (Volume fraction of water = 1): -0.01 m\/s <\/p>\n

<\/p>\n

             <\/p>\n

<\/p>\n

Thank you in advance!<\/p>\n
