A recent study co-authored by Dr. Nagarani Ponakala and Dr. Victor M. Job (and collaborators) from the Department of Mathematics in the Faculty of Science and Technology, The University of the West Indies, Mona explores the intricate dynamics of blood flow and oxygen transport through arteries affected by stenosis—a condition marked by the narrowing of arterial walls due to plaque deposits.

The research team constructed a mathematical model to describe the pulsating flow behaviour of blood and oxygen transport phenomena. The axial flow velocity was solved based on the regular perturbation technique, then the finite element method was used to compute the local oxygen concentration. The key factors influencing the blood flow velocity and oxygen concentration in the stenosed artery were studied. This study is significant not only in the evaluation of oxygen transport in diseased arteries with plaque deposits, but also in drug therapy regarding blood thinning medications. In particular, the results in this study were discussed in relation to coronary artery.
