dc.description.abstract | In this paper, the interaction between a plane Poiseuille channel flow and an
electroconvective movement induced by the electric field is numerically investigated. A
flow is generated by an inlet parabolic profile in a rectangular duct. Space charges are
injected in the flow through a metallic electrode placed on one of the channel walls and
brought to a given potential. Transient numerical simulations have been carried out to
investigate the structure of the flow. The entire set of the coupled Navier-Stokes and
EHD equations is solved using an efficient finite volume technique. The behavior of the
flow subjected to an applied voltage between the two electrodes is analyzed and time
evolution of the charge density distributions is presented. The interaction between the
convective movement induced by space charge injection and electric field and the
mainstream flow, emphasizes the appearance of periodic transverse traveling waves
convected in the channel. The dynamic of the flow through the variation of the ionic
mobility parameter M is investigated. For a given Reynolds number and ionoc mobility
parameter M it exists a threshold value Tc of the instability parameters T above which
the transverse traveling rolls appear or not. When T is increased, different flow regimes
have been highlighted starting from a complete steady state up to a fully unsteady
electro-plumes flow configuration. | es |
