← ScienceWhich outcome follows increased flow velocity through an aortic stenosis?
A)Increased turbulent kinetic energy dissipation✓
B)Decreased valve leaflet flutter amplitude
C)Augmented laminar boundary layer stability
D)Reduced downstream static pressure recovery
💡 Explanation
Increased velocity passing through a stenosis transforms laminar flow to turbulent flow, because the inertial forces overwhelm the viscous forces, leading to higher Reynolds number and transition caused by turbulent kinetic energy dissipation. Therefore, energy will be lost to turbulence rather than other effects.
