Description
This study examines the electro-osmotically modulated viscoelastic blood flow in arteries with both symmetric and nonsymmetric stenosis, accounting for heat generation and thermal buoyancy effects. Blood is modeled as a fractional second-grade fluid to more accurately capture its viscoelastic and memory-dependent behavior. The DebyeHkel linearization is applied to analyze the electro-osmotic effects. The governing partial differential equations are reduced to a system of ordinary differential equations using appropriate scaling transformations. Analytical solutions are derived for the resulting nondimensional boundary value problem. Key flow characteristics, such as axial velocity, temperature distribution, electric potential, volumetric flow rate, and wall shear stress, are computed and illustrated graphically using the Mathematica software. The computations reveal that axial velocity decreases near the arterial walls but increases in the core region for both symmetric (n = 2) and nonsymmetric (n = 6) stenoses with rising HelmholtzSmoluchowski velocity (UHs), CNT volume fraction (?), Debye length parameter (m), and stenosis height (e). Heat generation (? > 0) further enhances both velocity and temperature. Increasing ? reduces temperature and wall shear stress (?w), while higher flow rate (Q) and stenosis height (e) are elevated (?w). Nonsymmetric stenoses yield higher temperatures than symmetric ones. Trapping boluses grow in size and number with increasing Q for both stenosis types. These findings underscore the significant role of electro-osmotic and viscoelastic effects in hemodynamic regulation, with potential biomedical applications. World Scientific Publishing Europe Ltd.
