Which outcome results when exceeding a supercritical fluid engine heat exchanger's pressure limit?

💡 Explanation

Rapid temperature and flow fluctuations happens because exceeding of pressure limit causes resonant cavitation. Cavitation forms vapor bubbles due to localized pressure drops; therefore, extreme shifts in temperature and flow happen because of instability, rather than stable heat transfer rates.
