Numerical simulation of radiative flow with magnetized micropolar nanofluid along a curved stretched surface involving blood silica nanoparticles

Abstract

Silicon nanoparticles can be used as contrast agents in medical imaging procedures such as computed tomography (CT), magnetic resonance imaging (MRI), and fluorescence imaging. They can aid in the early identification and diagnosis of illnesses by enhancing image sensitivity and resolution through adjustable optical and magnetic properties. Additionally, the knowledge gathered from this research might help create cooling systems for electronics and thermal management applications that are more effective. The focus of current research is on the steady two-dimensional radiative flow of blood with silicon dioxide particles along a curved, stretched surface using a magnetized micropolar nanofluid. Furthermore, the effect of radiation is mentioned. Formulating a mathematical representation of flow equations requires the use of variables in curvilinear form. The leading PDEs are converted into nonlinear ODEs using the non-similarity approach. A bvp4c based on a three-stage Lobatto approach is used to solve the modified nonlinear ODEs. Numerical results for skin factor, couple stress, and local Nusselt number are presented in tabular form, and velocity, microrotation, and temperature fields are presented in graphs. The micro-rotation and temperature field exhibits a declining tendency with rising material parameters, whereas the velocity profile shows the opposite pattern. In addition, the significance of various physical characteristics under various parametric assumptions for a curved, stretched channel is reviewed and emphasized.
