  The present paper considers the flow of micropolar fluid through a membrane
modeled as a swarm of solid cylindrical particles with porous layer using the
cell model technique. Traditional boundary conditions on hypothetical cell
surface were added with an additional condition: the no spin condition / no
couple stress condition. Expressions for velocity and microrotation vector
components have been obtained analytically. Effect of various parameters such
as particle volume fraction, permeability parameter, micropolarity number etc.
on hydrodynamic permeability of membrane has been discussed.
