Scale-dependent Rayleigh-Taylor dynamics with variable acceleration by group theory approach
Snezhana Abarzhi, Kurt Williams
This work focuses on Rayleigh-Taylor instability (RTI)driven by acceleration with power-law time-dependence. We review the existing theoretical approaches, apply the group theory a…
WWhittle Maximum Likelihood Estimate of spectral properties of Rayleigh-Taylor interfacial mixing using hot-wire anemometry experimental data
David Pfefferlé, Snezhana I Abarzhi
Investigating the power density spectrum of fluctuations in Rayleigh-Taylor (RT) interfacial mixing is a means of studying characteristic length- and time-scales, anisotropies and…
Early- and late-time evolution of Rayleigh-Taylor instability in a finite-sized domain by means of group theory analysisAnnie Naveh
Annie Naveh, Miccal T. Matthews, Snezhana I. Abarzhi
We have developed a theoretical analysis to systematically study the late-time evolution of the Rayleigh-Taylor instability in a finite-sized spatial domain. The nonlinear dynamics…
On the Rayleigh-Taylor unstable dynamics of 3D interfacial coherent structures with time-dependent acceleration
Desmond L. Hill, Aklant K. Bhowmick, Snezhana I. Abarzhi
Rayleigh-Taylor instability (RTI) occurs in a range of industrial and natural processes. Whereas the vast majority of existing studies have considered constant acceleration, RTI is…
Deterministic and stochastic properties of self-similar Rayleigh-Taylor mixing induced by space-varying acceleration
Arun Pandian, Snezhana I. Abarzhi
Rayleigh-Taylor interfacial mixing has critical importance in a broad range of processes in nature and technology. In most instances Rayleigh-Taylor dynamics is induced by variable…
On the fundamentals of Richtmyer-Meshkov dynamics with variable acceleration
Aklant K. Bhowmick, Desmond L. Hill, Miccal Matthews +1
Richtmyer-Meshkov instability (RMI) plays important role in nature and technology, from supernovae and fusion to scramjets and nano-fabrication. Canonical Richtmyer-Meshkov instabi…
