Abstract: A heteroscopic turbine with a Knudsen number of less than ten. In one embodiment, the heteroscopic turbine generates a flow (7) from a gas. The turbine includes at least a moving surface (1) and a plurality of turbine blades (5, 11) on or in said surface. Each of the blades has a height comparable to a mean free path distance that characterizes molecules in the gas, and the blades are spaced apart by a distance comparable to the mean free path distance. In operation, the surface moves such that the turbine blades pass through the gas at a speed comparable to the mean thermal velocity. In different embodiments, the turbine can perform filtering of molecules in the gas based on direction and/or speed (velocity). Also, techniques by which such a turbine operates.

Abstract: Utility Model Patent for a hybrid turbine that consists in a Tesla turbine improved with the replacement partial or total of its smooth discs by innovative discs called 'Pelton type discs (2)'. The parts of the Tesla turbine are: stator, shaft, inlet, exhaust outlet (4) and smooth discs (2). The disc (2) with an innovative format, object of this patent, owns the characteristics of the Pelton Wheel, once it owns cavities (1) that are hit by the working fluid. The 'Pelton type' discs (2) have as purpose to increase the torque provided by the shaft of the turbine and it is an improvement of the Tesla turbine that makes it useful for many applications and improve its efficiency in applications which demands bigger torque that furnished by the original Tesla turbine. The proportion between 'Pelton type' discs (2) and smooth discs, used in the turbine, defines the increase of torque. The Hybrid Tesla-Pelton Wheel can be used like a pump, compressor or vacuum pump if operates in reverse way, that means, the working fluid goes into the openings near the centre (3) of the discs (2) and goes out at the ends of the discs (2) (effect that is obtained turning the shaft by a motor).

Abstract: The present invention relates to a rotary eddy machine that comprises a stator (1) and a rotor (2) separated by a toroidal working chamber (3). The chamber includes a plurality of vanes (4) and a separator (5) which are respectively connected to the stator and to the rotor. The working chamber communicates with a channel (6) formed in the rotor for supplying the working medium and with a channel (7) for discharging said working medium. The width of the working chamber section is equal to the difference between the maximal and the minimal radii of said chamber, wherein the radii correspond respectively to the distance from the axis to the most remote point of the working chamber and to the distance from the axis to the closest point of the working chamber. The ratio between the maximal radius of the working chamber (R) and the width of its section (h) is at least equal to 4.5 but does not exceed 9.5.
