Application of the Windkessel model on computational fluid dynamic simulations of the carotid bifurcation


Forn Cañabate, Francesc 


The main objective of this project is the correct implementation of the two-element Windkessel model in computational fluid dynamics simulations of the carotid artery bifurcation to improve the precision of the results obtained. To implement the conditions of the Windkessel model, an algorithm has been developed that has been applied to four carotid bifurcation geometries for which sufficient data were available. The algorithm has been solved by a discretization of the differential equation of the two-element model, and simulations have been carried out to determine the most appropriate values ​​for the Windkessel parameters, peripheral resistance and compliance. The implementation of compliance in computational fluid dynamics simulations allows considering the variations in volume that occur in the great arteries with pressure changes during the cardiac cycle. The results offer a first assessment of the potential improvement in computational fluid dynamics simulations by introducing Windkessel models.
