Stagnation point flow of γ-Al2O3 nanoparticles with suspension of blood and ethylene glycol materials: Thermal optimization through nonlinear radiative effects

The evaluation of heat transfer due to nanomaterials is crucial for advanced cooling performances, renewable energy systems, industrial heat exchangers and biomedical applications. The objective of this analysis is to investigates the enhancement of heat transfer due to γ − A l 2 O 3 with applications of nonlinear radiative, heat source and viscous dissipation. Stagnation point flow of γ − A l 2 O 3 has been examined in presence of velocity slip effects. Ethylene glycol (EG) and human blood are used as base materials with 50:50 % suspension of γ − A l 2 O 3 . Thermal properties are defined for hybrid nanofluid model. The problem is entertained in dimensionless form with help of suitable transformations. The numerical simulations of problem are performed with help of shooting technique. Comparative results are prepared A l 2 O 3 − b l o o d , A l 2 O 3 − E G , γ − A l 2 O 3 − b l o o d and γ − A l 2 O 3 − E G . The insight of problem is graphically visualized with associated applications. It is been examined that velocity profile enhances due to velocity ratio parameter. An improvement in temperature profile is observed due to Eckert number for both A l 2 O 3 and γ − A l 2 O 3 nanofluid. It has been further concluded that the heat transfer enhancement is larger for ethylene glycol based γ − A l 2 O 3 nanofluid.
