【 摘 要 】

Magneto-micropolar electrically conducting nanofluid flow over a linearly stretching sheet for heat and mass transfer in the presence of convective boundary condition is considered. In the energy equation, non-linear thermal radiation and Joule heating effects are incorporated. Velocity slip condition at the solid liquid interface is also employed. In the current model viscous dissipation and mixed convection aspects are also taken into account. Non dimensional ordinary differential equations are acquired by implementing the similar transformations on the governed partial differential equations. The shooting technique is utilized along with Runga-Kutta integration scheme to tackled the differential equations numerically. All the numerical calculations are further verified with MATLAB bvp4c scheme. Graphical results are exploited to view the behavior of emerging parameters on velocity, temperature and concentration of nanofluid. In limiting case, MATLAB code is verified with a published article and a good agreement is noted. Numerical computations are performed for the local Sherwood and Nusselt number and skin friction coefficients. It is observed that the electric field is dominant over the magnetic field. The behavior of velocity profile is reserved in the absence of the electric field. Further, the nonlinear thermal radiation aggregates the temperature profile.
