← ScienceWhich consequence results when supercritical fluid enters turbine passage?
A)Reduced isentropic turbine efficiency✓
B)Increased blade resonance frequency
C)Enhanced hydrodynamic lubrication regime
D)Decreased nozzle corrosion severity
💡 Explanation
Partial condensation causes reduced isentropic turbine efficiency through the mechanism of phase transition because non-equilibrium conditions quickly generate entropy within the flow path, therefore creating a lower overall quality steam rather than ideal energy-conserving expansion.
