dc.description.abstract | We study the linear stability and nonlinear behavior of the electroconvection between two concentric halfcylinders
with no-slip conditions on all boundaries. The no-slip condition makes impossible to apply the standard
modal approach. Hence, we apply a finite element technique similar to the one we have used in a previous
paper about the electroconvection in a rectangular enclosed domain. When compared to the classical problem of
electroconvection between two full concentric cylinders, the linear criterion is higher, due to the viscous shear
introduced by the lateral walls. As a consequence, the structure of the eigenmodes is very different. There is a
repulsion between modeswith the same symmetry, forcing pairs of modes to cross each other repeatedly. For inner
injection and small value of the ratio between the inner and outer radii the no-slip condition changes the nature
of the bifurcation from subcritical to supercritical, while it is always subcritical for outer injection. To understand
this behavior, we perform a modal analysis using the eigenfunctions obtained from the linear stability analysis
as modal basis. We show that the supercritical branch is originated by the nonorthogonality of the modes when
no-slip boundary conditions are imposed. These mechanism explains the previously unexplained appearance of
the supercritical branch in the enclosed rectangular configuration. | es |
