      How to find area of formed vena contracta and how to write an expression for emperical formula to calculate coefficient of discharge of an Orifice plate?

      You have iso-surfaces and clip options in Fluent to get planar surfaces representing the area over/under a certain value.
      The expression will be a function of the pressure etc on surfaces upstream and downstream of the orifice. You might need to create a report rather than an expression as you're after a single value based on surface data.
