Abstract EN
In the geophysical context, there are a wide variety of mechanisms which may lead to the formation of unstable density stratification, leading in turn to the development of the Rayleigh-Taylor instability and, more generally, interfacial gravity-driven instabilities, which involves moving boundaries and interfaces.
The purpose of this work is to study the level set method and to apply the process to study the Rayleigh-Taylor instability experimentally and numerically.
With the help of a simple, inexpensive experimental arrangement, the R-T instability has been visualized with moderate accuracy for real fluids.
The same physical phenomenon has been investigated numerically to track the interface of two fluids of different densities to observe the gravitational instability with the application of level set method coupled with volume of fraction replacing the Heaviside function.
Good agreement between theory and experimental results was found and growth of instability for both of the methods has been plotted.
