Firstly - FDM is suited only for structured, orthogonal meshes. FEM is used in some areas with success, but general application is problematic due to problems in derivation of a weak formulation for all the fancy equations arising in CFD. FVM is by far the most popular.

For a simple into to the three approaches see e.g.

Hope this helps
