Abstract
Entropy change of central black holes of accretion disks (including thin and thick disks) is investigated by considering both accretion and the Blandford-Znajek (BZ) process in detail. It is shown that the contribution of the BZ process to the rate of change of black hole entropy is always less than that arising from accretion process in the case of thin disks, while the former may be greater than the latter for a fast-spinning black hole surrounded by a thick disk. In addition the non-monotonic characteristics of the rate of change of black hole entropy in the BZ process are discussed.
