Numerical solution of micropolar fluid flow and heat transfer between two co-axial porous circular cylinders (Q1116757)

Classical Couette-Poiseuille shear flow and heat transfer in micropolar fluid between two co-axial porous circular cylinders under a constant pressure gradient when the outer cylinder moves parallel to itself with a uniform velocity, has been examined. The governing equations of momentum and first stress momentum are solved using Newton-Raphson method while the energy equation is solved using sweeping method. The velocity, microrotation and temperature distribution are displayed graphically. As compared to the Newtonian fluid, it is observed that for a positive pressure gradient the velocity and temperature both increase throughout the gap when the fluid is made more and more micropolar. The skin friction, couple stress and dimensionless rate of heat transfer on the walls are shown in tables.
