HOT GEOTHERMAL FLUID [4 records]

Record 1 1987-08-07

English

Subject field(s)
  • Geothermal Power Plants
CONT

Conductive geothermal systems are characterized by a thermal regime due to conduction alone, often in the steady state. The working fluid is either present(e. g. in geopressurized systems) or must be supplied(Hot Dry Rock Systems).

Record 2 1986-07-04

English

Subject field(s)
  • Thermodynamics
  • Oil and Natural Gas Extraction
CONT

The availability of such pumps would revolutionize both hot fluid transmission and geothermal power generation. This method of fluid transmission may soon become a reality, rather than a dream.

Record 3 1986-06-25

English

Subject field(s)
  • Turbines
  • Geothermal Power Plants
CONT

Bladeless turbine... An assembly of plain metallic discs is mounted on a shaft, with narrow spaces between the discs. Geothermal fluid-hot water and/or steam-is admitted to the spaces between the discs at the periphery, and is directed to follow an inward spiral path towards a central exhaust port. The driving force is derived from frictional boundary layer drag between the fluid(s) and the disc surfaces. Such a machine would be very cheap to construct and to maintain : the discs could easily be dismantled, cleaned of chemical deposits and reassembled.
