ABSTRACT

The steady mixed convection boundary layer flow of a micropolar fluid along a vertical cylinder is studied for isothermal as well as uniform surface heat flux boundary conditions. The transformed conservation equations of the nonsimilar boundary layers are solved numerically using the Keller box scheme. Numerical solutions for the velocity, angular velocity, and temperature fields are presented for different values of the material and mixed convection parameters. The wall shear stress and the surface heat transfer rate increase with buoyancy and cylindrical curvature.
