Virtual FFR Quantified with a Generalized Flow Model Using Windkessel Boundary Conditions

Figure 12

(a) Comparison between FFR values for Navier–Stokes model and non-Newtonian flow model combined with free outlets or Windkessel BC obtained by moving the sensor in the normal direction. (b) Comparison between FFR values for Navier–Stokes model and non-Newtonian flow model combined with free outlets or Windkessel BC obtained by moving the sensor in the tangential direction.
