| Planar convective flows in a porous annular enclosure are considered in the paper. A finite-difference scheme is developed for Darcy equations in polar coordinates.Approximations are constructed in order to preserve the discrete version of the cosymmetry. Numerical studies of the steady states families are presented. Instability of steady flows from the family is analyzed for different annular enclosures and branching-off of unsteady motions is examined. |
