Abstract: Turbine exhaust steam, axially fed between counter-rotating radial flow disk turbines, separates into: (1) a radially inward flow of low enthalpy dry steam, and (2) a radially outward flow of high enthalpy steam, noncondensibles, and condensate. The radially inward flow goes to a conventional condenser. The radially outward flow loses enthalpy turning the disk turbines as it passes in the boundary layers against the disks, thus becoming low enthalpy dry steam, and the counter-rotation of the disks by impinging mass flow of condensate, high enthalpy steam, and noncondensibles sustains a cascade of dynamic vortex tubes in the shear layer between the boundary layers. The low enthalpy dry steam resulting from work being done flows into the condenser through the vortex cores of fractal turbulence. Condensate exits the periphery of the workspace, ready to be pumped back into the Rankine cycle.

Abstract: Vortex gas separation is forced in radial counterflow between counter-rotating coaxial centrifugal impellers. Feed is at the axis of rotation. Axial extraction of nitrogen and water vapor is driven by an axial pump and by back pressure from the tank while radially outward flow of carbon dioxide and scrubbing targets is driven by the impellers.
