“…The research was then extended by Mousavi et al, [4], which the impact of radiation and suction were considered. The influence of radiation and slip factor on hybrid nanofluid flow over a permeable Darcy porous medium was observed by Bakar et al, [5]. Jamaluddin et al, [6] studied an incompressible Cross fluid over a shrinking sheet in the case of heat transfer properties in the presence of thermal radiation and suction effect.…”

This research studies the behaviour of hybrid nanofluid on mixed convection flow over a stretching sheet by considering the effect of non-uniform heat source/sink. The chosen base fluid is water with two different nanoparticles which are copper and aluminium oxide. The governing partial differential equations are reduced into ordinary differential equations using a similarity transformation technique. The resulting governing system then solved numerically using Keller-box method. The influence of space- and temperature-dependents of non-uniform heat source and sink parameters as well as the unsteadiness parameter is presented graphically. The current study shows that, the space- and temperature dependents of non-uniform heat source and sink significantly raises the fluid’s temperature. Comparative study also shows that hybrid nanofluid has higher temperature and heat transfer coefficient than single nanofluid and conventional fluid. It can also be concluded that, the enhancement of heat transfer rate can be achieved by reducing the parameter of space- and temperature dependents of non-uniform heat source and sink.

Purpose This paper aims to accentuate the behavior of second-grade hybrid Al2O3–Cu nanofluid flow and its thermal characteristics driven by a stretching/shrinking Riga plate. Design/methodology/approach The second-grade fluid is considered with the combination of Cu and Al2O3 nanoparticles. Three base fluids namely water, ethylene glycol (EG) and methanol with different Prandtl number are also examined. The formulation of the mathematical model of second-grade hybrid nanofluid complies with the boundary layer approximations. The complexity of the governing model is reduced into a simpler differential equations using the similarity transformation. The bvp4c solver is fully used to solve the reduced equations. The observation of multiple solutions is conducted for the assisting (stretching) and opposing (shrinking) cases. Findings The impact of suction parameter, second-grade parameter, electromagnetohydrodynamics (EMHD) parameter, velocity ratio parameter and the volumetric concentration of the alumina and copper nanoparticles are numerically analyzed on the velocity and temperature profiles, skin friction coefficient and local Nusselt number (thermal rate) of the second-grade Al2O3–Cu/water. The solution is unique when (static and stretching cases) while dual for a specific range of negative in the presence of suction effect. Based on the appearance of the first solution in all cases of, it is physically showed that the first solution is stable. Further examination reveals that the EMHD and suction parameters are the contributing factors for the thermal enhancement of this non-Newtonian working fluid. Meanwhile, the viscosity of the non-Newtonian fluid also plays a significant role in the fluid motion and heat transfer rate based on the finding that the EG base fluid produces the maximum heat transfer rate but the lowest critical value and skin friction coefficient. Originality/value The results are novel and contribute to the discovery of the hybrid nanoparticles’ performance in the non-Newtonian second-grade fluid. Besides, this study is beneficial to the researchers in this field and general audience from industries regarding the factors, which contributing to the thermal enhancement of the working fluid.

“…Beavers and Joseph [14] investigated the fluid flow over a permeable wall using slip boundary condition. The slip flows under different flow configurations have been studied by many researchers [15][16][17][18][19] in recent years.

The intention of this article is to investigate the impact of slip of MHD stagnation point flow over a permeable shrinking/stretching sheet with double stratification in a porous medium. Employing the appropriate similarity transformations and non-dimensional variables, the governing partial differential equations were reduced into a set of nonlinear ordinary differential equations. These equations were solved using shooting method and influence of pertinent variables on velocity, temperature and concentration are computed and analyzed. It was found that the slips have the propensity to control boundary layer flow and as the velocity slip increases, the momentum, thermal, and concentration boundary layer thickness become thinner for velocity slip. Therefore, velocity slip acts as a boost for enhancement of the velocity profile in the boundary layer region, whereas temperature and concentration profiles decelerate with the velocity slip. It is also shown that the skin friction coefficient has decreased as the values of velocity slip increase while the It was found that the slips have the propensity to control boundary layer flow and as the velocity slip increases, the momentum, thermal, and concentration boundary layer thickness become thinner for velocity slip. Therefore, velocity slip acts as a boost for enhancement of the velocity profile in the boundary layer region, whereas temperature and concentration profiles decelerate with the velocity slip. It is also shown that the skin friction coefficient has decreased as the values of velocity slip increase while the local Nusselt number and the local Sherwood number are increasing. A comparison with previous studies available in the literature has been done and found an excellent agreement by comparing the numerical results in two decimal places which supports the validity of the present analysis.
