  • Global instabilities in diverging channel flows 
    Swaminathan, Gayathri; Sahu, Kirti Chandra; Sameen, A; Govindarajan, Rama (Springer, 2011-06)
    A global stability study of a divergent channel flow reveals features not obtained hitherto by making either the parallel or the weakly non-parallel (WNP) flow assumption. A divergent channel flow is chosen for this study ...
  • Stability of a vortex in radial density stratification: role of wave interactions 
    Dixit, Harish N; Govindarajan, Rama (Cambridge University Press, 2011-07)
    We study the stability of a vortex in an axisymmetric density distribution. It is shown that a light-cored vortex can be unstable in spite of the 'stable stratification' of density. Using a model flow consisting of step ...
