Elemental mechanisms of hydrodynamic instabilities

  • D. Y. Hsieh


The elemental mechanisms for many hydrodynamic instabilities can be identified as negative damping, negative diffusion or ellipticity. Identifications of some well-known hydrodynamic instabilities are made. Model equations in connection with the instability associated with ellipticity should be studied more extensively.

Key Words
