Abstract
The present paper details a comparison of experimental and computational results for the electrovortex flow of mercury in cylindrical and semi-cylindrical vessels, which is driven by the direct electrical current supplied over top and bottom non-submerged electrodes. The time-averaged velocity of liquid metal computed using the LES model of turbulence qualitatively and quantitatively agrees with the measured profiles of the axial velocity for a cylindrical experimental setup. For a semi-cylindrical setup which represents possible ``cold'' physical modelling of MHD devices, the observed flow patterns at the free surface and the computed flow patterns also agree qualitatively.
