Absorption and dispersion of sound in reacting and relaxing fluids


Helman, William Phillip (1960) Absorption and dispersion of sound in reacting and relaxing fluids. Master's thesis, California Institute of Technology.


The hydrodynamic equations for a chemically reacting and internally relaxing fluid are obtained in a suitable form, and, are then used to find the dispertion and absorption of plane infinitesimal sound waves, Only the case of no viscosity, heat conduction, and diffusion is considered. It is shown that the interference effects between relaxation processes are not, in general, negligible compared to the relaxation effects themselves. A specific example, that of oxygen gas at 2500° K is considered giving an idea of the relative magnitudes of the several effects which are involved.
