← ScienceWhich risk increases if liquid-cooled turbine blades experience Leidenfrost effect?
A)Reduced heat transfer efficiency✓
B)Increased blade oxidation rate
C)Enhanced vibrational damping
D)Elevated compressive stress profiles
💡 Explanation
Inefficient cooling occurs because the Leidenfrost effect envelops blades in vapor. Thermal conductance sharply drops, therefore reducing heat transfer, rather than improving oxidation resistance due to gas film insulation.
