On the miscible Rayleigh–Taylor instability: two and three dimensions
On the miscible Rayleigh–Taylor instability: two and three dimensions
We investigate the miscible Rayleigh-Taylor (RT) instability in both 2 and 3 dimensions using direct numerical simulations, where the working fluid is assumed incompressible under the Boussinesq approximation. We first consider the case of randomly perturbed interfaces. With a variety of diagnostics, we develop a physical picture for the detailed …
