At the installation SOM, the experimental study of
the impulse acceleration influence on the behavior of
the turbulized layer obtained as a result of Rayleigh–Taylor
instability (RTI) action on the system of two different
density liquids with the density ratio n = 3,
has been performed. After application of impulse acceleration
the systems were moving according to inertia, and by using
the light method the coordinates of penetration of the
heavier liquid into the lighter one and vice versa
were determined. The liquids studied were placed inside
the ampoule that had internal working sizes (54 × 64
× 120) mm3. There were initial accidental
perturbations like a rough solid surface at the interface and the
width of the initial perturbation zone was L0
= 2.3 mm. The moving ampoule blow against metal plates created
the impulse acceleration. The relative impulse acceleration was
δg/g11 = 22.2–66.6 where
g11 is the ampoule acceleration before the
impact, the impulse duration was varied from 0.27 ms to 0.096 ms.
The results concerned with the turbulized layer extension after the
impulse acceleration action were obtained.
