Abstract
In the present numerical study, we consider a low-Prandtl liquid metal heated by Joule effect in a rectangular cavity with an aspect ratio of 2. The direct current provides heat to the process medium by a pair of plate electrodes, located at the cavity sidewalls. The simulations have been carried out using finite volume method for fixed values of the Prandtl number, Pr=0.01, and of the Rayleigh number, Ra=1.5×104, while the Hartmann number, Ha=1410, Comparison between the original noise-free data and cleaned data is explored. More precisely, accurate performances predicted using removing noise from numerical simulation data is obtained to define the inherently complicated nature of the competition of buoyancy with electromagnetic body forces.
