“…It follows from Bernoullis law for incompressible fluids, that reduction in cross-section area increases the velocity of fluid. This can also be supported by the fact that arteriosclerotic and thrombolytic arteries have higher blood pressure as compared to normal arteries [2]. Fig 4.9 shows graph of velocity of nanofluid (u) against radial direction (r) for different values of Grashof number (Gr).…”

This mathematical study comprising of a catheterized artery with clot and stenosis is conducted to highlight the usage of nanoparticles in treatment of thrombosis. Catheter coated with silver nanoparticles is inserted in the lumen of artery having clot and stenosis. The behavior of blood with nanoparticles is described using nanofluid. Navier-Stokes equation and diffusion equation for temperature as well as concentration are used to model the flow problem. Our prime intention is to study how concentration and nanoparticle size effect nanofluid flow considering the influence of various thermal features like thermal conductivity, specific heat capacity and thermal expansion. Solution has been obtained for concentration, temperature and velocity is obtained using finite difference method. The effects of radius of nanoparticle, Brownian motion parameter, stenosis depth, Grashof number and Darcy number have been examined graphically using MATLAB. It has been concluded that nanoparticles highly concentrate on the clot and stenosis and thus point to possible signicant use of nanoparticles in antithrombotic therapy. This model can be, thus, utilized in thrombolytic therapies by proper optimization of concentration of nanoparticles as well as their geometries.

“…As a result, the normal flow of blood in the artery wall is disrupted. Both blood flow and the magnitude of the flow rely on the height of the stenosis [5]. Misra and Chakravarty [21] found that improvement in stenosis height will decrease the amount of blood hematocrit in the stenotic area, resulting in reduced blood viscosity.…”

The diameter of an artery can narrow due to atherosclerosis or stenosis, making it challenging to resolve solute dispersion issues as blood flows via a stenosed artery. The stenosis occurrence restricted drug dispersion and blood flow. This research introduces the establishment of a mathematical model in examining the unsteady dispersion with respect to the solute in overlapping stenosis arteries depicting blood as a Herschel-Bulkley (H-B) fluid model. Note that fluid velocity was obtained by analytically solving the governing and constitutive equations. The transport equation has been solved by employing a generalised dispersion model (GDM), in which the dispersion process is described. Accordingly, yield stress, stenosis height, slug input of solute length, as well as a rise in the power-law index have improved the peak with regard to the mean concentration and solute concentration. The maximum mean concentration yielded the effective dose for therapeutic concentration. In conclusion, this study is relevant to disease arteries, coagulating hemodynamics and may help physiologists in furnishing a more refined understanding of diffusion processes in cardiovascular hydrodynamics. An interesting application related to the present study is the transportation of drugs in the arterial blood flow.
