← ScienceWhich risk increases when a sharp disturbance amplifies turbulence within a flowing jet fuel?
A)Accelerated fuel pump cavitation damage
B)Increased fuel system bulk viscosity
C)Enhanced laminar boundary layer formation
D)Reduced engine combustion stability✓
💡 Explanation
Increased turbulence intensity prematurely disrupts coherent flame kernel formation, leading to lean or rich blowout because the mixing process becomes unsteady. Therefore, engine combustion stability decreases, rather than promoting more stable behavior or affecting bulk fuel properties.
