← ScienceWhich outcome occurs when exceeding a liquid rocket engine's oxidizer pump threshold?
A)Turbulence induces cryogenic cavitation damage.✓
B)Increased efficiency of nozzle expansion.
C)Decreased thermal stress on chamber.
D)Laminar flow improves fuel mixing.
💡 Explanation
Exceeding thresholds generates excessive flow speeds. Intense turbulence then causes unstable vapor cavities to form if pressure drops locally; therefore cavitation damage occurs, rather than controlled nozzle expansion or improved flows, because of the fluid dynamic instability.
