← ScienceWhich outcome occurs when blood flow exceeds a Reynolds number threshold within a stenotic heart valve?
A)Laminar flow profile is restored
B)Valve leaflet adhesion likelihood decreases
C)Significant turbulent kinetic energy increases✓
D)Blood viscosity的影响 becomes comparatively negligible
💡 Explanation
Exceeding the critical parameter accelerates transition to turbulence due to inertial forces overpowering viscous damping via the Reynolds number. Specifically, transition of laminar flow to turbulent flow occurs because increased Reynolds stress drives localized kinetic energy increases; therefore significant turbulent kinetic energy increases, rather than laminar flow or lower viscosity effects.
