Reaction turbine operating on condensing vapors

A turbine, comprising:

• a housing having a first end wall, a second end wall and at least one sidewall extending between the first end wall and second end wall;
• an inlet in the first end wall;
• a shaft extending through the housing;
• a first partition dividing the housing into a first chamber and a second chamber, the first partition having an opening;
• a first compressor in the opening in the first partition;
• a rotor connected to the shaft in each chamber, each rotor having a first surface and a second surface, an inlet, an outlet and a channel extending between the inlet and outlet;
• a first horizontal partition forming a conduit between the inlet in the first end wall and the first surface of the rotor in the first chamber;
• a second horizontal partition forming a conduit between the opening in the first partition and the first surface of the rotor in the second chamber;
• and
• an exhaust in the housing.

A method of driving a rotor, comprising:

• introducing a fluid at saturation conditions to a channel in a rotor, the rotor having a throat having a decreasing cross section followed by an increasing cross section;
• overexpanding the fluid by the increasing cross section of the throat to a supercooled state;
• inducing condensation;
• raising the pressure and temperature of the working fluid with the heat released by the condensation step;
• and
• expanding the heated and pressurized fluid to produce work.
