Abstract
This paper focuses on advances in the understanding of both the fundamental and applied aspects of nanomaterials. Nanoparticles (titania and graphene oxide) in water-based fluid lying on a surface incorporating the leading edge accretion (or ablation) are analyzed. Entropy generation rate is also considered. The Hall current effect is induced in the flow of hybrid nanofluid, due to which the two-dimensional study converts into three-dimensional space. Similarity transformations convert the equations of momentum, heat transfer, nanoparticles volume fraction and boundary conditions into non-dimensional form. Mathematica software is used to obtain the computation through homotopy analysis method. Analysis is provided through the effects of different parameters on different profiles by sketching the graphs. Flow, heat transfer and nanoparticles concentration in TiO2/H2O, as well as GO-TiO2/H2O, are decreased with increasing the Stefan blowing effect, while entropy generation rate elevates upon increasing each parameter. Both of the velocity components are reduced with increasing the Hall parameter. Streamlines demonstrate that trapping is increased at the left side of the surface. The obtained results are compared with the published work which show the authentication of the present work.
Highlights
When an electrically conducting fluid is under an ionization process and the strength of the applied magnetic field is high, the normal conductivity of the magnetic field is reduced to the free spiraling of electrons and ions about the magnetic lines force before suffering collisions
The objective of the present study is to investigate further the hybrid nanofluid
An incompressible viscous fluid flow is investigated with free stream velocity U∞, nanoparticles concentration C and temperature T
Summary
When an electrically conducting fluid is under an ionization process and the strength of the applied magnetic field is high, the normal conductivity of the magnetic field is reduced to the free spiraling of electrons and ions about the magnetic lines force before suffering collisions. In such a situation, a current is induced in a normal direction to both the electric and magnetic fields. Shateyi and Motsa [1] analyzed the problem of magnetohydrodynamic flow and heat transfer of a viscous, incompressible and electrically conducting fluid past a semi-infinite unsteady stretching sheet. Ahmed and Zueco [3] obtained the exact solution to the problem of heat and mass transfer in a rotating vertical porous channel in the presence of Hall current
