Heat transfer analysis on Engine oil-based hybrid nanofluid past an exponentially stretching permeable surface with Cu/Al2O3 additives
The flow characteristic of the two-dimensional conducting hybrid nanofluid past an exponentially stretching permeable surface is analyzed. Flow through variable thicker surface for the free convective flow associated with transverse magnetic field in the flow phenomenon that enriches the study. The specialty of the model is the use of effective conductivity property considering the Mintsa model and the effective viscosity with the help of the Gharesim model for the enhancement of heat transport properties. Depending upon the recent applications related to industrial products, engineering as well as bio-medical science nanofluids are used as the best coolant. A comparative study is carried out for the transformed governing equations using both approximate analytical, that is, “Variational Iteration Method” (VIM), “Homotopy Perturbation Method” (HPM), and numerical techniques such as the in-build MATLAB command bvp5c. The simulated result in connection to the behavior of the physical parameters is deployed through graphs. The current outcomes validate the earlier established results in particular cases showing the conformity and the convergence of the methodology adopted. However, the observation shows that, shear rate retards with the significant enhancement in the particle concentration of the metal nanoparticles as well as the suction further the heat transfer rate enhanced. The fluid velocity profile boosts up for the increasing thermal buoyancy parameter whereas the reverse impact is rendered in the fluid temperature.
