  • Patent number: 4167371
    Abstract: A method and apparatus for transferring heat regeneratively in a rotating heat exchanger. The heat exchanger provides for the cold gas stream to be heated alternate compression and expansion with heat addition usually during the expansion phase of the compression-expansion step from a warmer fluid. The fluid to be heated is usually a gas, while the fluid releasing heat may be either a gas or liquid. The heat element is a folded member usually in the form of bellows mounted concentric with rotor shaft, with baffles within to provide for outward and inward movement of the gas. Due to the heat addition especially during the expansion steps, the gas to be heated gains in pressure and usually this pressure gain is work free, and in magnitude is similar to the constant volume heat addition pressure gain which is well known.

  • Patent number: 4012164
    Abstract: A method and apparatus for generating power and for pumping fluids, wherein a free vortex cavity, within a rotating rotor, is used to pressurize a fluid after which the fluid may be used as a pressurized fluid or be used to generate power. The working fluid is injected into the free vortex cavity through feed nozzles oriented to discharge the working fluid forwardly in the direction of rotation, so that the working fluid rotational speed is normally, at least in part of the cavity, greater than the rotational speed of the rotor. The working fluid is pressurized within the vortex cavity by being forced to follow a curved path. Part of the working fluid is taken near the periphery of the curved passage, and recirculated through nozzles located toward the rotor center from the periphery thus providing additional fluid flow within the free vortex cavity and improving the rotor performance.
