Abstract

Rayleigh-Taylor instability (RTI) is a classical hydrodynamic instability that occurs whenever two fluids of differing densities are accelerated against their density gradients. RTI's dynamic complexity, coupling of vastly different physical scales, and sensitivity to multiple parameters have obscured a number of key insights. Questions about the nature and number of scale-dependent solutions, the effect of initial conditions, and the nature of the late-stage mixing regime still abound. This thesis will attempt to examine the effect of interface morphology on the dynamics of RTI and assess whether interface morphology is a significant factor in the development and behavior of RTI.
