Which outcome occurs when a Stirling engine's regenerator matrix permeability decreases significantly?

💡 Explanation

When regenerator permeability decreases, heat transfer resistance increases because the obstruction limits convective flow, hindering optimal temperature gradients and regenerative heat recapture and leading to lower efficiency. Therefore reduced heat transfer occurs, rather than higher power, stability, or reduced leakage, all requiring unobstructed regenerator function.
