← ScienceWithin a Sterling cryocooler, which outcome increases during free-piston adiabatic phase transitions?
A)System exergy destruction✓
B)Isothermal efficiency reduction
C)Regenerator thermal capacity
D)Compressor workload reduction
💡 Explanation
Increased entropy occurs because thermodynamic irreversibilities manifest; therefore, system exergy destruction increases, rather than decreasing workload. Expansion work generation efficiency decreases, increasing entropy in the cooling stage.
