Implication

Transitional models may enhance CFD accuracy for carotid WSS; leaves open effects on clinical risk stratification.

Structured PICO

Population

Magnetic-resonance (MR) image-based model of a carotid bifurcation with 70% stenosis reconstructed using realistic patient-specific conditions

Intervention

Transitional version of Menter's hybrid k-epsilon/k-omega shear stress transport (SST) model and its 'scale adaptive simulation' (SAS) variant

Comparator

Laminar flow model and standard turbulence models

Outcome

Prediction of blood flow patterns including velocity profiles, wall shear stress, and turbulence intensitysurrogate

Transitional turbulence models provide more accurate predictions of wall shear stress and flow patterns in stenosed carotid arteries compared to standard laminar models.
