Which risk increases when a heat exchanger's cold-side fluid undergoes a phase transition to vapor?

💡 Explanation

When the cold-side fluid transitions to vapor, nucleate boiling causes a vapor film to form on the heat transfer surface, reducing the effective temperature gradient because of limited turbulent mixing. Therefore a reduced heat transfer coefficient results, rather than increased corrosion, over-pressurization, or vibration, which require different operational mechanisms.
