Thermal enhancement of micropolar tri hybrid nanofluid (CuO−MgO−TiO2/blood) due to stretched surface with modified non-Fourier model

Owing to growing demand of energy-efficient thermal systems, the hybrid nanomaterials have emerged as next-generation medium of heat transfer due to significant thermal features. The hybrid nanofluids offers impressive applications in energy sectors, thermal management systems, cooling processes etc. This continuation presents enhanced thermal aspects of micropolar tri hybrid fluid confined by a stretching surface. The suspension of coper oxide (CuO), magnesium oxide (MgO) and titanium oxide (TiO 2 ) nanoparticles with human blood base fluid is used to focus the tri hybrid nanofluid properties. The governing expressions of energy equations are modified by including the Cattaneo-Christov model. The thermal radiation applications with nonlinear modelling are used for enhancement of heat transfer. After modelling the problem, the numerical simulations are performed via shooting scheme. The investigation of heat transfer is visualized for tri hybrid nanofluid (CuO−MgO−TiO 2 /blood) and hybrid nanofluid (MgO−TiO 2 /blood). The findings reveal that microrotation velocity profile enhances for micropolar fluid parameter. A progressive change in heat transfer is exhibited due to nanoparticles volume fraction. Furthermore, the Nusselt number increases numerically against thermal relaxation parameter and micropolar fluid parameter. The proposed results confirm applications in advanced thermal systems, chemical systems, heat exchangers, energy storage units etc.
