    Notes: Summary  A Theoretical analysis is carried out to study the boundary-layer flow over a continuously moving surface through an otherwise quiescent micropolar fluid. The transformed boundary-layer equations are solved numerically for a power-law surface velocity using the Keller-box method. The effects of the micropolar K and exponent m parameters on the velocity and microrotation field as well as on the skin-friction group are discussed in a detailed manner. It is shown that there is a near-similarity solution of this problem. The accuracy of the present solution is also discussed.

    Three-dimensional darcian free convection near a stagnation point on an isothermal surface (1987)
    Springer
    Transport in porous media 2 (1987), S. 357-362 
    Details
    ISSN: 1573-1634
    Keywords: Convection at a stagnation point ; boundary layers in porous media
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Technology
    Notes: Abstract The unsteady free convection boundary-layer flow in a fluid-saturated porous medium near a general three-dimensional stagnation point is considered. It is shown that the problem can be reduced to an equivalent two-dimensional problem by a simple transformation of variables. The form of solution then depends only on the sign of the quantity a + b, where a and b are the principal curvatures of the body at the stagnation point.

    Mixed convection in a porous medium produced by a line heat source (1995)
    Springer
    Transport in porous media 18 (1995), S. 1-13 
    Details
    ISSN: 1573-1634
    Keywords: Mixed convection ; thermal plume ; line source ; porous media

    Topics: Geosciences , Technology
    Notes: Abstract A boundary-layer analysis is presented for the mixed convection flow which is produced when a horizontal line heat source, which is embedded in an infinite fluid-saturated porous medium, generates heat at a constant rate. It is shown that the governing equations can be non-dimensionalized so that they do not involve any parameters and thus just one solution of the transformed boundary-layer equations is required. Series solutions which are valid both near the line source and far downstream are obtained and compared with the numerical solution of the full boundary-layer equations.
