Abstract

In this paper, a mathematical model has been developed for studying unsteady blood flow through the stenosed vessel under different density variation due to antiplatelet drug. Blood flowing through the artery is considered to be Newtonian. By considering 25% and 90% dilations in arteries, expressions for the velocity profile, wall shear stress, streamline pattern and pressure gradient have been derived numerically under finite volume method. The above said quantities are computed for a specific set of values for different parameters involved in the model analysis. This serves as an illustration of the validity of the mathematical model developed here. The results estimated on the basis of the computation are presented graphically. The obtained results for different parameters involved in the problem show that the flow is appreciably influenced by density variation at different time seconds.
