Abstract

Energy is extracted from a high-temperature high-pressure working fluid by augmenting flow of the working fluid with a flow of gas having a molecular weight less than the fluid, utilizing some of the energy from the working fluid to induce addition and mixture of the gas in an ejector creating a flow of the mixed fluids having a greater mass and lower temperature than the initial flow of working fluid and supplying the mixed fluids to a turbine which converts the energy in the mixed fluids into mechanical energy. The exhausted fluids are separated and at least the augmenting gas is recycled to the ejector. The gas is selected from the group consisting of hydrogen, helium, nitrogen, air, water vapor, or an organic compound having a molecular weight less than the working fluid, and the working fluid is selected from the group consisting of an inorganic element, an inorganic compound, or a fluorocarbon.
