Convective heat transfer in an electrically conducting micropolar fluid at a stretching surface with uniform free stream

The problem of convective heat transfer for a micropolar fluid in the presence of uniform magnetic field is investigated near an isothermal-stretching sheet. This has been done under the effect of buoyancy force. The sheet is linearly stretched in the presence of a uniform free stream of constant velocity and temperature. Numerical solutions for the governing boundary layer equations for a range of values of magnetic, vortex viscosity and microrotation parameters, also, Grashoff number obtained by applying an efficient numerical technique based on shooting method. The effects of these parameters examined on the velocity of fluid, temperature distribution and angular velocity of microstructures as well as the coefficient of heat flux and shearing stress at the plate.
