ABSTRACT:
A method and apparatus for generating power by passing a fluid from a higher energy level to a lower energy level by compressing said fluid first in a continuous flow centrifuge rotor and then reducing the pressure of said fluid in an inward flow reaction turbine section. The fluid enters the first rotor at center and leaves the second rotor at center, and vanes are provided within both rotors to assure that said fluid will rotate with said rotors. Nozzles are provided near the periphery of the first rotor to increase the absolute tangential velocity of the fluid leaving said first rotor; the tangential velocity of second rotor near rotor tip is greater than said first rotor tangential tip velocity. The said fluid is contained within said rotors, and passes from said second rotor to said first rotor near rotor center. Heat is being added to said fluid near the first rotor periphery, and heat is being removed from said fluid near the center of said first rotor; both heat addition and heat removal are mainly conducted during said compression of said fluid. Said fluid is normally a gas, and said heat addition and removal are usually conducted by using a second fluid which may be a gas or a liquid, and a third fluid which may be also a gas or a liquid.
