Fatima Zohra Kadid - Rachid Abdessemed - Saïd Drid

   This article presents the study of an unsteady fluid flow in a MHD pump fed with sinusoidal current at variable frequency for mercury pumping using an alternate coupling finite element and volume computation with an adaptation of the nodes. By introducing vector potential A, the vorticity ξ and the stream function ψ, a system of equations which are of the elliptic type for describing the velocity and pressure distribution in the channel is obtained. The calculation results are presented and the study of the influence of the frequency is also considered.
