← ScienceWhich outcome arises when a low-friction Stirling engine operates near theoretical Carnot efficiency?
A)Isothermal heat transfer becomes infinitely slow✓
B)Adiabatic compression generates excessive material stress
C)Regenerator matrix suffers thermal fatigue cracking
D)Volumetric swept area approaches zero
💡 Explanation
Perfect Carnot efficiency requires isothermal processes, but isothermal heat transfer needs infinite time to occur with a finite temperature difference; the finite temperature gradient lowers performance because irreversible expansion supplants theoretical equilibrium, rather than increasing stress.
