ON THE DISPERSAL OF ACOUSTIC WAVES BY RADIATIVE TRANSFER OF HEAT,
Abstract
It is shown that the assumption of specific heat ratio near one simplifies the analysis of plane sound waves subject to energy addition dependent on temperature, and in the case of radiative energy exchange in a fairly transparent gas, a third-order differential equation is obtained. Solutions are presented for an impulsively moved piston. In a very hot gas, an optically thin wave, dispersing as though by relaxation, is embedded in an optically thick wave dispersing as though by conduction. The cool-gas case is also analyzed. It is concluded that only in a very hot gas would dispersion be observed terrestrially. (Author)
