Investigation of nonlinear radiative effects and shape features in stagnation point flow of hybrid nanofluid (Al₂O₃–SiO₂)/(C₂H₆O₂–blood): Non‐Fourier heat transfer model

Abstract The investigation of heat transfer due to hybrid nanofluid near the oblique stagnation point flow has novel industrial and thermal applications. Such a configuration arises in the aerodynamic surfaces, like aircraft and turbine blades. The improvement in transport processes due to hybrid nanomaterials is important for thermal management in high‐performance systems. The current investigation seeks to explore heat transfer management in oblique stagnation point flow of hybrid nanomaterial impacted with nonlinear radiated effects. The suspension of hybrid nanofluid is assumed to be the decomposition of aluminum oxide (Al 2 O 3 ) and silicon oxide (SiO 2 ) nanoparticles with human blood and ethylene glycol (C 2 H 6 O 2 ). A non‐Fourier model, namely, the Cattaneo–Christov approach, is implemented to modify the energy equation. The flow problem is truncated into dimensionless form by entertaining appropriate variables. The numerical simulations for such a system are accomplished with the shooting method. The comparative thermal simulations are detected for mono nanofluid (MNF) and hybrid nanofluid (HNF). The analysis for the Nusselt number and wall shear force is observed graphically. It has been examined the obliquely velocity declined for free stream stagnation flow coefficients. Boosted variation in heat transfer is noticed against the surface heating parameter and the radiated phenomenon. The claimed results present significance in automotive industries, solar processes, heat exchangers, thermal management systems, cooling phenomenon, and so forth.
