  I am working on natural convection heat transfer in a 2D square enclosure whose vertical walls are maintained at different constant temperature and horizontal walls subjected to conductive heat flux boundary condition.
  
  I am facing problem to consider conductive heat flux boundary condition on the horizontal walls for the 2D geometry.
  
  Please help me

  If you're using Fluent read up on Shell Conduction.

  Actually I thought to consider shell condition but I found that shell conduction is applicable for only 3D geometry. Can I apply shell conduction for 2D?

  Oops, yes 3d only. I rarely use 2d so hadn't noticed the restriction.
  
  Your options are then to create the model one cell thick and use symmetry on the "front" and "back" or use a thin solid zone for the metal part. For the former make sure the domain thickness doesn't give you high aspect ratio cells.
