Numerical simulations demonstrated that oscillatory shear index and wall shear stresses are extensively governed by the degree of stenoses, with recirculation bubbles varying by Reynolds number.

May refine computational models of stenosis flow; leaves open clinical outcome validation.
Numerical simulations using patient-specific pulsatile profiles highlight the critical role of stenosis severity and Reynolds number on arterial wall shear stress and oscillatory shear index.
Bit et al. (2014) studied Stenosed artery. Degree of stenoses (25% to 80%) and flow Reynolds number was evaluated on Temporal and time averaged wall shear stress, oscillatory shear index and pressure drop. Numerical simulations demonstrated that oscillatory shear index and wall shear stresses are extensively governed by the degree of stenoses, with recirculation bubbles varying by Reynolds number.
