Which outcome occurs when a Stirling engine's regenerator experiences increased internal gas leakage across phase boundaries?

💡 Explanation

When gas leaks across the regenerator's phase boundaries, energy is transferred bypassing the intended heat exchange, because convective heat transfer is compromised, reducing the thermal efficiency of heat recovery and storage. Therefore reduced efficiency results, rather than increased power, lowered temperature or improved starting which depend on effective heat regeneration.
