Abstract
This study aims to explore the flow characteristic of a nanofluid (๐ด๐‘ข/๐ต๐‘™๐‘œ๐‘œ๐‘‘) containing gyrotactic microorganisms flow through an artery exhibiting mild stenosis. This study finding provide significant insights into the interaction with magnetic field parameter, temperature-dependent viscosity, viscous dissipation, Arrhenius energy, heat source parameter and the nanofluid. The governing flow equations are converted into the dimensionless form using the appropriate similarity transformations. The resulting partial differential equations are subjected to numerical investigation employing the explicit FTCS (forward time central space) numerical technique within the computational framework of MATLAB.

The major findings are that the increment in the thermal Grashof number leads to rise in the velocity and volumetric flow rate. The increment in the Rayleigh number leads to decline in the velocity profile. The results demonstrate that an increase in the activation energy parameter reduces the Sherwood number and enhances the concentration profile. The current effort holds promise for the advancement of biomedical device design. It offers valuable insights into hemodynamic flow, applied therapeutically within the biomedical sciences.
