Note on the Helmholtz instability in stratified flows with magnetic fields

  • A. Satya Narayanan
Letter to the Editor


The nature of the neutral curves for the stability of a Helmholtz velocity profile in a stratified, Boussinesq fluid in the presence of a uniform magnetic field for the cases (1) an infinite fluid (2) a semi-infinite fluid with a rigid boundary is discussed.
