Significance of multiple slip and nanoparticle shape on stagnation point flow of silver-blood nanofluid in the presence of induced magnetic field

Abstract

Non-spherical nanoparticles have gained popularity for their ability in changing the thermophysical properties of a nanofluid. The current work focuses on studying the significance of multiple slip and nanoparticle shape on stagnation point flow of blood-based silver nanofluid considering chemical reaction, induced magnetic field, thermal radiation, and linear heat source which is beneficial in cancer therapy, biomedical imaging, hyperthermia, and tumor therapy. Relevant similarity transformations are effectuated in converting the mathematically modeled governing equations into a system of ODEs and are then numerically resolved in MATLAB employing the adaptive Runge-Kutta method and the Newton Raphson method. Observations on the consequence of differing parameters on varying attributes are achieved via tables and graphs. Additionally, the shape effect of nanoparticles on various attributes is also evaluated. Linear heat source and thermal radiation parameters exhibit a constructive effect whereas the thermal slip parameter exhibits a destructive effect on temperature. Further, it is observed that the blade-shaped nanoparticle exhibits the greatest heat transfer rate followed by platelet, cylinder, and spherical-shaped nanoparticles, respectively.
