Computation analysis of unsteady second grade biomagnetic micropolar blood base nanofluid flow with motile gyrotactic microorganisms

The primary aim of this research is to investigate the impact of an external magnetic field on bacteria that are surrounded by a large quantity of magnetite nanoparticles. The study utilizes magnetite Fe3O4 nanofluid using blood as a base fluid with variable thermal conductivity, in which a synthetic bacterium moves within a biological cell. The focus of the study lies in analyzing the non-steady movement of a micropolar fluid in a two-dimensional context, specifically in the presence of a curved porous wall. Suitable transformations are used to transform the nonlinear PDEs to their corresponding nonlinear ODEs. The HAM (Homotopy Analysis Method) is used to find the mathematical results. The impact of various key parameters is studied by using numerical tables and graphs. This study shows that the velocity curves of the pure blood is higher than those magnetite/blood. Clinical disease shows that perilous tumors have weakened blood flow. This study demonstrates that higher parameter values lead to an improvement in the blood velocity profile, indicating that medication therapy reduces tumor size and aids in countering distorted cells. Furthermore, the research reveals that an increase in the concentration of magnetite nanoparticles corresponds to an increase in the distribution of blood temperature. The findings of this study highlight the significant role played by thermal conductivity in enhancing the rate of heat transfer.
