Numerical study of heat transport mechanism in hybrid nanofluid [(Cu-Al₂O₃)/water] over a stretching/shrinking porous wedge

The numerical exploration of the dynamics of hybrid type nanofluid (Cu-Al2O3)/water over a fascinating domain of stretching/shrinking porous wedge is performed. The problem is designed and studied numerically by fluctuating the flow parameters. From the results, dominant behavior of stretching/shrining and suction/injection parameters observed on the velocity field. These are prominent at the wedge surface due to significant influence of suction/injection and stretchable characteristics of wedge. Further study revealed that (Cu-Al2O3)/water has better conductive characteristics than normal Cu/water due to optimum dominant thermophysical values of hybrid nanoparticles. The temperature drops prominently for lambda with stretching of wedge. Further, injecting fluid from the wedge surface favors the temperature variations. Finally, the results aligned with published data under certain feasible conditions and found that the conducted study is valid.
