ABSTRACT:
The utilizable energy of a working fluid is converted into mechanical energy by means of friction forces exerted by the fluid on the moving walls of one or a number of circulation ducts forming part of a rotor. In their respective azimuthal projections, the friction force exerted on the fluid by the duct walls and the Coriolis force to which the fluid is subjected are of the same order of magnitude. The method consists in varying the pressure of the working fluid which is circulated in a spiral circuit and subjected to azimuthal displacements in the same direction of rotation as the rotor when the fluid comes closer to the axis and in the opposite direction when it moves away from the axis. When at least a portion of the duct walls forms part of a heat exchanger, the working fluid can also undergo predetermined variations in entropy and in enthalpy.
