dc.description.abstract | This work addresses the stability of a two-dimensional plane layer of a dielectric liquid enclosed in wall
bounded cavities of different aspect ratios and subjected to unipolar injection of ions. Numerical simulations
have been conducted to investigate the effect of lateralwalls, especially in the development of the electroconvective
instability. It is found that an unexpected change of the bifurcation nature occurs for certain cavity aspect ratios.
We showthat above the linear stability threshold for the rest state a supercritical bifurcation arises. This bifurcation
takes place at a given value Tc1 of the parameter T (the electric Rayleigh number). Then, a second subcritical
bifurcation occurs at a second threshold Tc2, featuring a typical hysteresis loop with an associated nonlinear
criterion Tf , which is very characteristic of the Coulomb-driven convection. This behavior has been confirmed
by different numerical codes based on different numerical methods. The physical mechanism which leads to this
situation is analyzed and discussed. The evolution of the bifurcation diagrams with the aspect ratio of the cavity
is also provided and analyzed. | es |
