    Flow of micropolar fluid through a porous tube of varying cross-section in the presence of magnetic field
    (Selcuk University Research Center of Applied Mathematics, 2012) Srinivasacharya, D.; Shiferaw, Mekonnen
    The steady flow of incompressible and electrically conducting micropolar fluid through a tube with permeable wall of slowly varying cross-section is studied. The fluid motion is subjected to an external uniform magnetic field directed transverse to the flow direction. Assuming small aspect ratio and neglecting the inertia terms, a closed form solutions are obtained for velocity and microrotation components. The profiles of velocity and microrotation components presented for differentmicropolar fluid parameters, magnetic parameter and wall absorption parameter. The variation of wall skin friction is presented graphically for different flow geometries.

    Unsteady flow of micropolar fluid through a circular pipe under a transverse magnetic field with suction/injection
    (Selcuk University Research Center of Applied Mathematics, 2010) Murthy, J. V. Ramana; Bahali, N. K.; Srinivasacharya, D.
    In this paper, we consider the unsteady flow of an incompressible electrically conducting micropolar fluid through a circular porous pipe subjected to periodic suction/injection at the walls of the tube and in the presence of a transverse magnetic field. Under the Stokesian assumption and using the similarity transformations, the stream function and microrotation components are obtained in terms of Bessel's functions. The variation of skin friction with respect to micropolar parameters and Hartman's number, suction parameter are studied and depicted through graphs.
