Steady Mhd Flow of Micropolar Fluid between Two Rotating Cylinders with Porous Lining
نویسندگان
چکیده
The steady flow of an electrically conducting, incompressible micropolar fluid in a narrow gap between two concentric rotating vertical cylinders, with porous lining on inside of outer cylinder, under an imposed axial magnetic field is studied. Beavers and Joseph slip condition is taken at the porous lining boundary. The velocity profiles, coefficient of skin friction on the cylinders are calculated. The effects of Hartmann number, the porous lining thickness parameter, coupling number, couple stress parameters and Reynolds number on azimuthal velocity, micro-rotation component and coefficient of skin friction on cylinders are depicted through graphs.
