Abstract: A centrifugal gas compressor with rotating hollow housing and an independently rotating, turbine compresses gas bubbles in capillary tubes and recovers energy from the liquid drain (sometimes a liquid recycler). The housing rotatably retains an internal spool having the turbine. Gas-liquid emulsion fed to the capillaries generates compressed gas-liquid emulsion at a radially distal annular region in an annular lake within the spool. Compressed gas leaves the lake and is ported away. A turbine blade edge in spilt over liquid drives the turbine, converting angular velocity/momentum into shaft torque as recovered energy. Blade captured liquid is recycled to capillary inputs.

Abstract: The gas compression method/system restricts flow of emulsified liquid-gas mixture through many substantially radial capillary tube-passages in a rotating disk by either one-way valves, narrowing the passages, hydraulic impedance and/or reinforcement of coriolis forces in terminal end tail segments of the capillary passages. Compressed gas is released from peripherally collected compressed gas-liquid emulsion (beyond the terminal ends of the tubes) in a arcuate peripheral disc space when the compressed gas bubbles emerge from the peripherally collected emulsion. A compressed gas drain draws off gas from the peripheral space. Liquid drain draws off liquid from the space. In different embodiments, radial outboard flow through the capillaries is effected by various one-way valves which may be a single valve in the passage or multiple valves. Coriolis force in tail segments is enhanced by angular displacement in the direction of rotation. Valves may be used in combination with such tail-end segments.
