摘要

Quadratic thermal radiation is important in current fluid dynamics, especially in biomedical transport issues when temperature gradients are big enough to render linear radiation models unsuitable. The present study investigates the role of UO2–MoS2–MgO–TiO2 nanoparticles mixed in blood with bio-magnetic Casson mixed nanofluid flow through a stretching cylinder along with Heat source/sink and quadratic thermal radiation. The leading governing highly nonlinear partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) by using similarity variables. The dimensionless ODEs are employed BVP4c method in MATLAB tool. The final outcomes of the important physical parameters are further explained by graphs using energy and velocity profiles. In addition, increasing the magnetic field parameter values increases the velocity profile. Increasing the curvature parameter values increases the temperature profile. Rising the radiation parameter values enhances the temperature profile. This approach is useful for magnetic guided and controlled biomedical flow and thermal regulation systems. Blood/UO2–MoS2 exhibits superior thermal conductivity and reduced adhesion compared to Blood/MgO–TiO2. The present study uses in biological processes including hyperthermia medication, laser-assisted treatments, tumor photothermal therapies, vascular circulation, and healthcare device refrigeration, asymmetric radiative heat exchange improves thermal forecast accuracy.
