Although the thermal Comptonization theory has been quite successful in describing the high energy spectra of black hole candidates there are still a number of unresolved issues. Due to the turbulent nature of the accretion disk and high radiation pressure in the vicinity of the black hole, it seems "natural" for the disk to possess a corona. However, neither the geometry nor the heating mechanism of such a corona are known. In bulk Comptonization models a purely radial flow of plasma has been considered, making the assumption that the radiation force on the accreting matter is negligible. On the other hand, a general agreement on the presence of an accretion disk exists. In this work we show that Comptonization in a rotating flow can also give rise to power-law spectra. Soft photons get upscattered by collisions with fast-moving electrons, which follow Keplerian trajectories in the accretion disk.
