Abstract:
Steady incompressible micropolar fluid in a two - dimensional uniform channel
with a stenosis under the influence
of magnetic field has been investigated. Assuming the
stenosis to be mild, the flow equations have been solved using slip condition and the
expressions for the resistance to flow and the shear stress have been derived. The effects
of various parameters on these flow variables have been studied. It is found that the
resistance to. flow as well as the shear stress increases the height of the stenosis and
decrease with micropolar parameter. The effects
of other parameters on resistance to flow
and the sheer stress also have been considered.
