    Abstract
  • In this research, we experimentally investigated the characteristics of the turbulent mixing zone induced by Rayleigh-Taylor (R-T) instability under different accelerations.We used the high-speed shadowgraph to study the evolution of the interface composed with the silicone oil/potassium iodide solution, and analyzed the width of the mixing zone and the obliquity of the interface quantitatively.According to the experimental results, the difference in the evolution of width between horizontal interface and oblique interface exhibits mainly in late stage, and the evolution law is basically same with that in the early and middle stages.There are two different trends in the evolution of the interfacial obliquity.The interfacial obliquity increases with time parabolicaly at first, and then increases linearly.As a result, the fluid interface turns over in the later stage of evolution.There is a competitive relationship between the turbulent mixing induced by R-T instability and K-H instability respectively.
