Abstract
Conditions are derived for dynamically stabilizing the Rayleigh-Taylor instability of a fluid interface and for attaining the corresponding dynamic equilibrium. These conditions could be proved in experiments using an aqueous solution of Potassium Jodide (ρ h=1.6 g/cm3) as the heavy fluid and oil (viscosity SAE 140,ρ ι =0.9 g/cm3) as the light one. Parametric resonances were suppressed, but could be observed using oil of lower viscosity.
