Shape features in magnetized hybrid nanofluid subject to thermal radiation, viscous dissipation and chemical effects: Insight to nanoparticles morphology

Abstract

The hybrid nanomaterials are advanced working fluids that offer enhanced thermal impact due to combination of multiple nanoparticles. Owing to improved thermal features, the hybrid nanofluids are assumed to be ideal for enhancing the heat transfer phenomenon in various thermal systems, solar energy, cooling processes, heat exchangers and nuclear systems. Current study explores the thermal management of magnetized hybrid nanofluid with applications of non-classical Fourier approach. A uniform decomposition of titanium dioxide (TiO₂) and silicon dioxide (SiO₂) nanoparticles with human blood base fluid has been assumed. The improvement of heat transfer is further analyzed by contributing the nonlinear thermal radiation and viscous dissipation effects. The concentration of nanofluid with applications of chemical reaction features is accounted. The mathematical model is developed by following famous Tiwari and Das model. The flow is subject to porous stretched surface subject to realistic engineering, industrial and biomedical engineering. The dimensionless form of problem is retained with implication of scaling parameters. The resultant system is solved numerically via the shooting method coupled with the Runge-Kutta technique, ensuring high accuracy and computational efficiency. Physical insight of key parameters has been examined graphically. The results show that consideration of nonlinear thermal radiation as well as viscous dissipation substantially enhances the transport phenomenon. The change in chemical reaction parameter reduces the concentration phenomenon. Furthermore, the combined impact of magnetohydrodynamics (MHD) and surface permeability alter the flow dynamics, offering valuable insights for optimizing processes in advanced thermal management systems and petroleum engineering.
