droplet impact on a dry surface.... VOF again

rogerspass · August 26, 2011, 20:20

Hi. All,
I know there are some topics related to this droplet impact on a dry surface using VOF. But I still get lost. My question is how to setup the boundary conditions.

In more detail, for a positive to the right and up respectively coordinate, I create a 2D rectangular face domain, 10mm (L) x 5mm (W), where a 2mm water droplet is located in the center. Both faces are using 0.1 interval size of mesh. I set the the four boundary as walls, also set the droplet as a velocity inlet. The multiphase (VOF) was used. Gravity is point to -Y. After setting a velocity (Vy = -1 m/s) for the droplet in Fluent and proceed the calculation. The droplet just did not move at all. Can someone shade me some light? Do I miss something else? Thanks.

Hi rogerspass
Did you recieved any answer on your query, I have almost the same problem, if you know how to simulate droplet impact on solid surfcae please help me.
With best regards
