← ScienceWhich outcome results when exceeding a diesel fuel injector's design Re number in the supply line?
A)Increased turbulent kinetic energy✓
B)Decreased boundary layer thickness
C)Enhanced laminar flow stability
D)Minimized pressure drop effects
💡 Explanation
Increased turbulent kinetic energy results because exceeding the Reynolds number threshold promotes transition to turbulence. This transition increases shear stress and energy dissipation via viscous effects, therefore turbulent kinetic energy increases in the fuel, rather than remaining as flow energy.
