Grahic Jump Location
Relations for the calculation of the specific enthalpy of the superheated vapor hg using the enthalpies of the saturated vapor hgs and the ideal gas vapor hId
Grahic Jump Location
The compressibility factor Zg is obtained by modifying a linear approximation for compressibility at temperature T/Tcr=5 with a correction ΔZ depending on the compressibility factor of the saturated vapor Zs
Grahic Jump Location
(a) The original definition array and (b) the formed regular computational array for pressure. The dashed line defines the envelope of the real physical data.
Grahic Jump Location
Grid for a passage between the turbine stator vanes. The flow is from lower left to upper right.
Grahic Jump Location
(a) Inflow and (b) outflow conditions of the turbine stator passage nondimensionalized by the throat values
Grahic Jump Location
(a) Mach number (b) density, (c) pressure, and (d) temperature distributions in the turbine stator. The nondimensional contour interval is 0.1 in the Mach plot, 0.01 in the density and pressure plots, and 0.02 in the temperature plot.
Grahic Jump Location
