| Abstract: | Summary The problem of steady laminar hydromagnetic flow in a porous annulus of different permeability in the presence of a magnetic field is considered and solved by a method of perturbation. The case when the injection or the withdrawal rate at the outer wall, depending on the sign of the normal velocity at this wall, is greater than or equal to such rate at the inner wall is given in details. Some numerical results regarding the friction coefficients at the walls and the axial pressure coefficient and velocity distribution have been appended. |
