Magnetized blood-based Casson ternary hybrid nanofluid flow over a wedge with Darcy-Forchheimer resistance and nonlinear thermal radiation

The heat transfer analysis and flow of a blood-based tri-hybrid nanofluid over a stationary wedge in a Darcy-Forchheimer porous medium is investigated with the effects of an applied magnetic field and nonlinear thermal radiation. With the dispersion of tri-hybrid nanoparticles consisting of - - in blood-based fluid to augment its thermal conductivity, the biomedical applications of physiological base fluid are realistically captured. The transformed system of nonlinear ordinary differential equations was obtained utilizing the standard appropriate similarity transformations, and numerically solved by employing the Chebyshev Collocation Method (CCM) implemented in Mathematica 14.1. The effects of different associated physical flow parameters on the momentum field, thermal profile, local skin friction, and Nusselt number were examined. The findings presented that with a rise in the nonlinear thermal radiation parameter, the thermal profile significantly enhances near the midpoint due to the augmented thermal energy transport within the blood-based suspension. Furthermore, higher Darcy and Grashof numbers accelerate the velocity distribution by reducing porous medium resistance and strengthening buoyancy-induced motion of the blood-based tri-hybrid nanofluid. In contrast, fluid motion is significantly suppressed by the combined linear and inertial drag forces associated with an intensified Darcy-Forchheimer porous medium. Beyond its potential applications in advanced thermal management and energy transport technologies, the proposed fluid model offers valuable insights for the design and optimization of biomedical systems, including magnetic hyperthermia, targeted drug delivery, bioheat regulation, and other blood-assisted therapeutic applications.
