Abstract: The effect of time-periodic vertical gravity modulation on the onset of thermosolutal convection in an infinite horizontal layer with stress-free boundaries is investigated using Floquet theory for the linear stability analysis. Situations for which the fluid layer is stably stratified in either the fingering or diffusive regimes of double-diffusive convection are considered. Results are presented both with and without steady background acceleration. Modulation may stabilize an unstable base solution or destab… Show more

“…Murray et al 6 considered the effect of gravity modulation on the onset of convection for the unidirectional solidification problem. Saunders et al 7 studied the effect of gravity modulation on the stability of a horizontal double-diffusive layer. These authors considered a fluid layer of stress-free boundaries with linear temperature and solute concentration distributions that would generate instabilities either in the finger or the diffusive mode.…”

“…Double-diffusive convection is of practical importance in many research areas, which involve convective heat and mass transfer. Saunders et al [3] have discussed the effect of gravity modulation on thermosolutal convection in an infinite layer of fluid. Rogers et al [4] have observed superlattice patterns in vertically oscillated Rayleigh Benard convection.…”

“…It should be indicated that Saunders et al [14] studied the same problem without Soret effect; they further considered the stress-free case. A list of useful papers on the applied aspect of solidifications under the effect of vibration may be found in [14].…”

A list of useful papers on the applied aspect of solidifications under the effect of vibration may be found in [14]. Also, Jue and Ramaswarmy [15] study numerically the thermo-solutal convection in a confined cavity in the Rayleigh-Bénard geometry.…”
