ON THE ENERGY EQUATION FOR A SPATIALLY DEVELOPING INSTABILITY WAVE IN THE THEORY OF HYDRODYNAMIC STABILITY
-
Abstract: In the literatures of theory of hydrodynamic stability, energy equation is often being used. However, the energy equation for a spatial mode problem was always simplified by neglecting a term representing the work done by the pressure. In this article, it was. shown by numerical examples that such a treatment is in general unjustified.
