Scientific paper

In this paper we investigate the possibility of the analog of a phenomenon like superradiance, that is, amplification of a sound wave by reflection induced by a rotating acoustic black hole in the fluid "draining bathtub" model in the presence of a disclination and analyze the role played by this object in which concerns the amplification or reduction of superradiance with the deficit angle.
