Abstract: Recently a number of new power cycles have been proposed in which heat rejection as well as heat addition has been at supercritical pressure. Although a number of working fluids have been ...

Abstract: This paper reports upon a continuing investigation into the Joule-Thomson effect in H2 O. The values of μ are computed over a wide range of temperature and pressure using two independent ...

Abstract: Over a broad range of temperatures and pressures the Joule-Thomson coefficients have been computed from the enthalpy equations developed by the International Formulation Committee, 1967. The ...

Abstract: A cycle is proposed in which no condenser cooling water is required. Turbine back-pressure is kept to conventional levels by condensing the steam during the evaporation of a refrigerant. Heat ...

Abstract: The specific heat ratio γ, was measured in low-pressure superheated steam, using a modified form of the free expansion experiment performed originally by Clement and Desormes. Values for γ are ...

Abstract: A dimensionless ratio is proposed relating isenthalpic and isentropic changes in real gases. The new parameter meets the requirements for a property, and is shown to depend only upon the ...

Abstract: The design of an apparatus for determination of Joule-Thomson coefficients is presented. An axial flow porous plug is utilized and the downstream flow is so arranged that one concentric flow ...

Abstract: This paper reports upon an experimental investigation in which a heat-transfer instrument was designed, built, and applied in a rarefaction wave tube. An analysis of the heat-transfer instrument ...

Abstract: The regenerative turbomachine was investigated as a pressure-increasing device, using both air and water as working fluids. Three machines were involved, representing two geometries. A non-dimensional ...
