RISTwo-Dimensional, Nonequilibrium, Wet-Steam Calculations for Nozzles and Turbine Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes a method of computing nonequilibrium, steady flows of wet steam in two- and quasi-three-dimensional turbine cascades. The mixture conservation equations are solved in an ...
Critical Conditions and the Choking Mass Flow Rate in Nonequilibrium Wet Steam Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical analysis of choking in steady, one-dimensional, nonequilibrium, wet steam flows is presented. It is shown that such a flow becomes choked when the vapor phase velocity attains the ...
An Equation of State for Steam for Turbomachinery and Other Flow Calculations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large-scale equations of state for steam used for generating tables are unsuitable for inclusion infinite difference flow calculation computer codes. Such codes, which are in common use in the ...
Condensation in Jet Engine Intake Ducts During Stationary Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes an analysis of the condensation of moist air in very long intake ducts of jet engines during stationary operation. Problems arising from such condensation include fan overspeed ...
Nonequilibrium Throughflow Analyses of Low-Pressure, Wet Steam Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes a throughflow computational method that combines wet steam theory with an axisymmetric streamline curvature technique in order to predict nonequilibrium effects in low-pressure ...
Defining the Efficiency of a Cooled Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Despite 40 years development of gas turbine cooling technology, there is no general agreement on the most appropriate definition of cooled turbine efficiency; the critical issue is the choice ...
A Detailed Three-Dimensional Simulation of an IP-SOFC Stack
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A typical integrated-planar solid oxide fuel cell (IP-SOFC) consists of modules with series connected electrochemical cells printed on their outer surfaces. Oxygen is supplied to the cathodes ...
Nonequilibrium Streamline Curvature Throughflow Calculations in Wet Steam Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes a computer program which combines the streamline curvature throughflow calculation method with one-dimensional wet steam theory. Two subsonic applications are described in detail: ...
Diffusion and Chemical Reaction in the Porous Structures of Solid Oxide Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Rolls-Royce integrated-planar solid oxide fuel cell (IP-SOFC) consists of ceramic modules with electrochemical cells printed on the outer surfaces. The cathodes are supplied with oxygen from ...
The Deposition of Fog Droplets on Steam Turbine Blades by Turbulent Diffusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical approach for calculating the rate of deposition of fog droplets on steam turbine blades by turbulent diffusion is described. The theory is similar to that which has proved ...
