Abstract: A method and apparatus for the generation of power in a turbine, wherein a gaseous working fluid is passed within a rotor to compress the working fluid and then the fluid is accelerated and then decelerated to generate said power. Heat is added to the working fluid usually before said deceleration, and heat is usually removed from the working fluid after said deceleration. The turbine also is provided with regeneration means where heat is exchanged between streams of the working fluid within the rotor. The working fluid may be sealed within the rotor or be supplied from external sources. The turbine can also be used for heat transfer work with the reversal of rotation, if desired.
Abstract: A vortex tube construction in which the cold and hot fluids are recirculated to the inlet and energy is extracted from or added to the fluids either by heat exchange or by mechanical removal. This concept is adapted for other devices in which a flow of substantially homogeneous fluid is divided into separate flows at different energy levels.
Abstract: A method and apparatus for a thermodynamic machine for the generation of power or for the transport of heat, where a compressible working fluid is compressed and expanded in a cycle using a vane type apparatus. Heat is added and removed from the working fluid by using another fluid within the vane unit housing together with the working fluid. The second fluid is also circulated through external heat exchange means for changing the temperature of the fluid. The working fluid may be a suitable gas, such as a halogenated hydrocarbon or carbon dioxide, and the second fluid may be a liquid such as a light oil which also can provide lubrication within the housing. The working fluid ordinarily remains within the vane type unit housing, while the second fluid is circulated through the outside heat exchanger means.
Abstract: The closed gas turbine plant is fitted with at least one by-pass valve serving as an adjusting member for the working medium cycle, and uses measuring transformers for measuring the working medium cycle high and low pressures as well as the actual and nominal speeds of the turbine. A regulator has a first regulator part including an integrator, and the difference signal, between the speed nominal value and the speed actual value, is processed in this first regulator part. The regulator has a second regulator part in which signals representative of the working medium cycle high pressure and the working medium cycle low pressure are combined in an adding manner and the output signals of the two regulator parts are supplied to a third regulator part which controls the by-pass valve or valves.
Abstract: A method and apparatus for generating power by passing a motivating fluid from a higher energy level to a lower energy level by compressing said fluid within a centrifuge type first rotor and discharging said fluid via nozzles near the first rotor periphery forwardly in the direction of rotation to a second rotor which is an inward flow type reaction turbine, then passing said fluid through a regeneration type heat exchanger to transfer heat from the inward bound fluid into outward bound fluid, after which the fluid is cooled in a heat exchanger to its original temperature and is passed outward again thus completing its cycle. Heat is added to said fluid near the periphery of the second rotor, or the heat may be added near the periphery of the first rotor, or both. Additionally, the fluid may be supplied to the unit from outside source, and returned to such outside source, and the cooling thus may be eliminated from the unit. Further, the entering fluid from outside source may be at an elevated pressure.
