Fluid Dynamics,pears that, for subsonic flow, there can be no wave propagation because of the different character of the partial differential equations (PDEs) that govern the flow. Transonic flow involves a transition between subsonic and supersonic flow. Steady flows in which this transition occurs are called mix

Wave Propagation in Elastic Media, physics of a given situation in the sense that from these conservation equations, which are called the field equations, we can obtain the velocity, pressure fields, etc., which give the wave properties. Since the field equations were couched in the Eulerian coordinates, the various fields that were

Variational Methods in Wave Phenomena,e equation defining the medium. In the global approach used here certain ., which arise from energy considerations, are to be minimized. A functional is a function of a function, and is defined by a certain integral whose integrand involves a class of functions, one of which minimizes the functional.

The Physics of Wave Propagation,physics: conservation of mass or continuity, conservation of momentum, and conservation of energy. These will be discussed in this chapter, the mathematical formulation being treated from the point of view of physics.
