Theoretical studies on linear shear instabilities often use simple velocity and density profiles
(eg, constant, piecewise) for obtaining good qualitative and quantitative predictions of the
initial disturbances. Furthermore, such simple profiles provide a minimal model for obtaining
a mechanistic understanding of otherwise elusive shear instabilities. However, except a few
specific cases, the efficacy of simple profiles has remained limited to the linear stability
paradigm. In this work, we have proposed a general framework that can simulate the fully …
