RÉSUMÉ
In this work, a numerical investigation has been performed to examine the spatio-temporal characteristics of mixed convective heat transfer of liquid metals in square enclosures with external time-dependent body forcing. An explicit finite-difference code on a collocated grid has been used to solve the Navier-Stokes and energy equation subject to Boussinesq approximation. A spatially localized external forcing covering a broad range of wavenumbers and amplitude has been applied at a fixed Rayleigh (Ra = 10) and Prandtl (Pr = 0.01) numbers. The investigations reveal that significant increase in heat transfer rates can be achieved depending on the wavenumber and amplitude of forcing.
