Numerical outcomes for the steady and unsteady flow situations are investigated for the mixed convection flow of Casson nanofluid caused by the motion of a nonlinear stretching sheet in porous media with chemical reaction and magnetic effects. In the present study, the impact of convective boundary conditions on the thermal and concentration profiles as well as in the presence of Brownian motion and thermophoresis effects on the flow field are also examined. Highly non-linear and coupled partial differential equations (PDEs) are transformed into a system of ordinary differential equations (ODEs) by using suitable similarity transformations and subsequently portray numerical and graphical results with the help of bvp4c tool using MATLAB. The validity of numerical results are compared and checked with previously published results in the literature. For deliberating the physical nature of the investigation, graphical and tabulated results are provided. The Casson parameter helps to reduce the intensity of the skin friction, while Casson fluid has a converse impact on velocity and temperature field, but parallel results are seen in the case of concentration and temperature profile. The impacts for the magnetic parameter on velocity and temperature is revealed more effective than nanoparticle concentration. The impact of thermal and concentration buoyancy parameter on velocity, temperature and concentration profiles are observed and found that velocity profile increases with slight increase in thermal buoyancy parameter but decreases the other two profiles.

“…It was observed by the authors that rate of heat transfer in case of Cu nanofluid is more than Al 2 O 3 . Suction/injection impacts on Casson and unsteady tangent hyperbolic nanofluid with gyrotactic microorganisms along a wedge was studied by Jabeen 41 and Shahzad et al 42 Here are some of the important recently conducted studies [43][44][45] related to nanofluid flows along a stretching sheet. Halim et al 46 explored the Powell-Eyring nanofluid at a stagnation-point past a vertical stretched surface with buoyancy force thermophoresis/ Brownian motion active and passive controls.…”

An unsteady mixed convectional boundary layer flow of a Casson nanofluid having magnetic ( Fe3 O4) and non-magnetic ( Al2 O3) nanoparticles suspension within two different types of base fluids, water (Newtonian) and sodium alginate (non-Newtonian), which incorporates viscous dissipation effects over a nonlinear stretching sheet with magnetic field effects. Some suitable non-dimensional similarity transformations are applied to convert the governing coupled nonlinear partial differential equations into a set of ordinary differential equations and then solved by using differential transformation method in association with Pade-approximation. A comparison has been made with already published results to assure the validity and reliability of the computational results, good agreement is found between the current and previous studies. The impacts of different physical parameters active on flow, temperature, and nanoparticle concentration have been discussed both numerically and graphically. The impact of radiation, internal heat sink/source, viscous, and ohmic dissipation was discussed for magnetic and non-magnetic nanofluid categories. We have also presented the tabular results of various emerging parameters to discuss the nature of skin friction, Nusselt, and Sherwood numbers. It was observed that performance of non-Newtonian (sodium alginate) fluid in heat and mass transfer is slightly better than Newtonian (water) based fluid but no major difference was seen in heat and mass transfer when comparison was made with magnetic and non-magnetic nanoparticles.

“…Atif et al, [37] discussed the effect of variable thermal conductivity and thermal radiation on MHD tangent hyperbolic fluid past a stretching sheet. Recently, Shahzad et al, [38] presented their numerical study for an unsteady tangent hyperbolic nanofluid flow pas a wedge in the presence of suction or injection. Some generalized Newtonian rheological models usually describe the blood viscosity and chemical materials processing applications: the Carreau model, the Carreau-Yasuda model, etc.…”

The purpose of this study is to investigate the boundary layer of Carreau fluid and heat transfer over an exponentially stretching plate derived in a vertical porous with variable surface thermal flux. The partial differential equations that represent the momentum equation and heat equation are commuted into nonlinear ODEs by applying similarity transformations and results found numerically. The impact of several emerging dimensionless parameters labelled the Weissenberg number (We), the power-law index ( ), Velocity slip ( ), Thermal jump ( ), and Prandtl number ( ) on the velocity profile and heat transfer on the boundary layer are showed in detail. In more detail, also the influence of physical parameters on local skin friction and Sherwood number are studied. The shooting method with the explicit technique is used to find the solution and all results are illustrated graphically and numerically. We noted that by increasing power index, radiation parameter and velocity slip, the velocity profile increases, and the temperature profile decreases. Furthermore, it is deduced that rising the thermal radiation parameter reduces the local Nusselt number.
