← ScienceWhich outcome results when injection fuel flow's Reynolds number in a Diesel engine's nozzle exceeds design limits?
A)Laminar flow becomes increasingly turbulent✓
B)Viscosity increases and dampens fluid
C)Erosion decreases from stable flow
D)Fuel atomization efficiency increases sharply
💡 Explanation
Transition to turbulence occurs because exceeding Reynolds number limits causes increased inertial forces relative to viscous forces, therefore greater instability, rather than remaining in stable, predictable laminar flow regimes; viscosity doesn't change proportionally.
