← ScienceWhich consequence results when turbulence abruptly intensifies within an aircraft's jet engine combustor?
A)Increased fuel-air mixing efficiency
B)Elevated engine vibration and stall✓
C)Uniform temperature distribution profile
D)Decreased NOx pollutant formationrate
💡 Explanation
Intensified turbulence introduces unsteady flow and pressure fluctuations because `turbulent combustion instability` amplifies pressure waves; therefore, vibration and potential stall increase, rather than leading to ideal fuel-air mixing under controlled conditions.
