“…They found that an enhancement in the Eckert number increase in the energy profile while the concentration profile declines gradually. Vijayalaxmi et al 21 reported the convective heat transfer of the stagnation point flow of the magnetohydrodynamic MHD Eyring-Powell nanofluid fluid over exponential stretching sheet. The thermal radiation effects is discussed by many authors.…”

The heat and mass transfer of a magnetohydrodynamic micropolar Carreau nanofluid on a stretching sheet has been analyzed in the presence of induced magnetic field. An internal heating, thermal radiation, Ohmic and viscous dissipation effects are also considered. The system of the governing partial differential equations is converted into the ordinary differential equations by means of the suitable similarity transformation. The resulting ordinary differential equations are then solved by the well known shooting technique. The impact of emerging physical parameters on the velocity, angular velocity, temperature and concentration profiles are analyzed graphically. The dimensionless velocity is enhanced for the Weissenberg number and the power law index while reverse situation is studied in the thermal and the concentration profile.

“…Numerical study of MHD Casson fluid with slip boundary and Joule heating was analyzed by Kamran et al [31] with the main finding that an increment in the Reynolds number enhances the entropy of the system. Vijayalaxmi et al [32] observed the stagnation point flow of MHD Eyring-Powell nanofluid with convective conditions past an exponential stretching sheet. Effect of Joule heating and viscous dissipation on MHD flow and melting heat transfer over a stretching sheet was observed by Kumar et al [33] with main finding that the fluid and the dust phase temperature was enhanced as the Eckert number is enhanced.…”

The forthright intention of this communication is to scrutinize the effect of variable thermal conductivity and thermal radiation on the magnetohydrodynamic tangent hyperbolic fluid in the presence of nanoparticles past a stretching sheet. For heat and mass transport phenomena, the collective stimulus of slip and convective conditions with the internal heating, viscous dissipation and Joule heating have been taken into account. The boundary layer equations of two-dimensional tangent hyperbolic nanofluid have been established with the help of boundary layer approximations. With the assistance of appropriate similarity transformation, the governing set of PDEs are rendered into the coupled nonlinear ODEs. The solution of the resulting ODEs is obtained with the help of the shooting technique. Furthermore, an authentication of the computed results is obtained through benchmark with the previously reported cases. The influence of various pertinent parameters on the velocity, temperature and concentration profiles has been analyzed graphically and discussed. The physical behavior of the velocity, temperature concentration, skin friction coefficient, the Nusselt and the Sherwood numbers have been investigated diagrammatically for various pertinent parameters. It is observed that the velocity profile is declined for the growing values of the Weissenberg number and the power law index, whereas the thermal and concentration fields are observed to enhanced for the same parameters. Our analysis depicts that the temperature and the concentration profiles are enhanced for the slip parameter and the Eckert number.

The aim of the present study is to analyze the magnetohydrodynamic micropolar Carreau nano uid ow past a stretching sheet. Viscous dissipation, internal heating, Joule heating, and linear thermal radiation e ects are also incorporated into the energy equation. The system of governing PDEs is transformed into the ODEs by invoking the similarity transformation. The shooting method is implemented to solve the system of ODEs. The in uence of pertinent parameters on ow distributions is analyzed graphically and discussed in detail. The uid motion upsurges for the larger values of the Weissenberg number and the material parameter, while the reverse situation is studied in the thermal and concentration pro les.
