Evaporation of water and then condensing the vapor on the top condensation surface

Please login with a confirmed email address before reporting spam

facing issues in carrying out the simulation due to lack of knowledge. please direct me how can i simulate the following problem.

The Geometry

I have a solar still which is in form of 2D shape of trapezium. the bottom surface is parallel to the ground. there are two surfaces which are parallel to each other and are perpendicular to the bottom surface and forms the wall of the still and are the other two sides of the trapezium. the top surface is slant in nature.

The Initial Conditions

Water is filled in the solar still to a height of around 1% of the taller wall, measured from bottom. Heat is given from the bottom surface so as to heat the water in the still to form vapor.

What i want the simulation to do.

I want that the water which evaporates from the base of the still should get condensed on the top slant surface of the still and then slowly drips back down.

Please tell me how can I simulate this in COMSOL.
