This study focuses on the Couette flow of micropolar fluid in a rotating annulus region filled with porous medium, comparing the motion of micropolar fluid under spin and no-spin conditions, with implications for engineering applications.
The present work concerns with the Couette flow of micropolar fluid in rotating annulus region which is filled with the porous medium. The aim of this study is to present the differences in the motion of micropolar fluid under two different sets of boundary conditions i.e. spin and no-spin condition. An analytical approach has been used to obtain the solution for the linear velocity, microrotational velocity, shear stress and couple stress of the micropolar fluid flowing through annulus porous region. The significance of this work is that the use of two sets of boundary condition greatly impacts the motion of the fluid inside the porous annulus region. The main conclusion withdrawn from the present work is that under the spin condition, the velocity profile achieve lower values as compared to the velocity profile under the no-spin condition. The reverse result has been found for the microrotational velocity of the micropolar fluid. The obtained results can be used in various industrial and engineering applications. The present work is validated with the previously published work.
