← ScienceWhich flow regime arises when the Reynolds number increases within an aerospace hydraulic actuator?
A)Increases flow-induced vibration✓
B)Laminar-to-thermal gradient reduction
C)Stable fully laminar region
D)Increased pump head resistance
💡 Explanation
Increased Reynolds number indicate greater inertial over viscous forces, leading to transition from laminar to turbulent flow which, because it increases fluctuating pressures and forces, therefore increases flow-induced vibration, rather than steady laminar damping.
