Nonlinear convective oscillations in two-layer systems with different aspect ratios

Nonlinear oscillatory convective flows, developed under the joint action of buoyant and thermocapillary effects in the 47 v2 silicone oil-water system with different layers thicknesses, are investigated. Nonlinear simulations have been performed for twodimensional flows. Transitions between oscillatory convective regimes with different symmetry properties and steady flows, have been studied. It is found that the oscillatory motion is observed in a finite interval of the Grashof number values. © Springer Science+Business Media B.V. 2012.SCOPUS: ar.j
