Abstract
The forced convective boundary layer flow of electrically conducting micropolar fluids has been investigated in the presence of magnetic field applied in the normal direction of a sheet that shrinks or stretches horizontally and thus causes the fluid motion. Self-similar transforms have been employed to convert the governing partial differential equations into ordinary differential form. The resulting highly non-linear model has been solved numerically with coding in Mathematica. Rigorous computational work has been carried out for sufficient ranges of the parameters of the study namely suction parameter S, stretching/shrinking parameter ∈ , magnetic parameter M, material constants d1, d2, d3 involved in micromotion, heat source parameter B, radiation parameter Rn, heat flux parameter n and Prandtl number Pr. The effects of these parameters on the physical quantities like skin friction coefficient, velocity, temperature and micromotion are presented graphically.
