We investigate various boundary conditions in two dimensional turbulence systematically in the context of conformai field theory. Keeping the conformai invariance, we can either change the shape of boundaries through finite conformai transformations, or insert boundary operators so as to handle more general cases. Effects of such operations will be reflected in physically measurable quantities such as the energy power spectrum E(k) or the average velocity profiles. We propose that these effects can be used as a possible test of conformai turbulence in an experimental setting. We also study the periodic boundary conditions, i.e. turbulence on a torus geometry. The dependence of moduli parameter q appears explictly in the one point functions in the theory, which can also be tested.
