MHD forced convective boundary-layer flow of a micropolar-nanofluid from a stretching sheet

A theoretical study is considered to investigate forced convective boundary layer flow of a micropolar-nanofluid (Al₂O₃/water) due to an exponentially stretching sheet in the presence of suction and transverse magnetic field. The governing equations are first cast into a dimensionless form by a similar transformation and the resulting equations are then solved numerically by using the Runge-Kutta numerical integration, procedure in conjunction with shooting technique. The velocity, temperature and microrotation profiles were computed for various values of nanoparticles volume fraction φ, suction parameter f_w, magnetic field parameter M and vertex viscosity parameter Δ. The obtained results are shown graphically followed by a quantitative discussion. Comparisons with previously published works are performed and excellent agreement is obtained.
