A turbine rotor has a spiral involute channel formed in a rotor disk. In one embodiment, the channel has an inlet near the center of the disk and an outlet near the periphery of the disk. Working fluid of the turbine enters the channel at the inlet and is directed along the channel where kinetic energy of the working fluid is transferred to the rotor by way of blades positioned within the channel. A series of rotors may be stacked together to form multiple, parallel flow paths through a turbine.
