Effect of Catheter and Stenosis on Solute Diffusion in Non-Newtonian Blood Flow through a Catheterized Stenosed Artery

The presence of stenosis at the wall artery lead to further cardiovascular diseases such as heart attack, stroke and many more. Treatment a stenosed includes insertion catheter through which affects blood flow solute dispersion. This present study focuses on effect radius height dispersion behavior. problem is modelled using Herschel-Bulkley fluid represent rheology, with boundary conditions. Analytical solutions in integral form are obtained by solving momentum equation constitutive equation. integrals numerically evaluated Simpson’s 3/8 rule Regula-Falsi method obtain velocity. velocity employed into unsteady convective-diffusion solved generalized model (GDM) analyse behaviour diffusion. influence diffusion coefficient mean concentration observed. Results show that decreases increases. A decrease simultaneously increases concentration.
