Abstract
The proficiency of hybrid nanofluid from Cu-Al2O3/water formation as the heat transfer coolant is numerically analyzed using the powerful and user-friendly interface bvp4c in the Matlab software. For that purpose, the Cu-Al2O3/water nanofluid flow between two parallel plates is examined where the lower plate can be deformed while the upper plate moves towards/away from the lower plate. Other considerable factors are the wall mass suction/injection and the magnetic field that applied on the lower plate. The reduced ordinary (similarity) differential equations are solved using the bvp4c application. The validation of this novel model is conducted by comparing a few of numerical values for the reduced case of viscous fluid. The results imply the potency of this heat transfer fluid which can enhance the heat transfer performance for both upper and lower plates approximately by 7.10% and 4.11%, respectively. An increase of squeezing parameter deteriorates the heat transfer coefficient by 4.28% (upper) and 5.35% (lower), accordingly. The rise of suction strength inflates the heat transfer at the lower plate while the presence of the magnetic field shows a reverse result.

Using the spectral relaxation method, Oyelakin et al.[4] solved the Buongiorno’s model of Casson nanofluid flow with the inclusion of slip and convective conditions, magnetic field and thermal radiation. Further assessment of the nonlinear radiation and magnetic field effects have been conducted by Acharya et al.[24] for hybrid Ag-Fe3O4/kerosene nanofluid flow over a permeable stretching sheet. The Cu-Al2O3/water hybrid nanofluid flow past an exponentially stretching/shrinking surface was recently studied by Wahid et al.[25,26]
