Excerpt from The Effects of Viscosity and Heat Conductivity on the Transmission of Plane Sound Waves, And, Decay of Spherical Sound Pulses Due to Viscosity and Heat Conductivity The usual theory of shock wave propagation omits the effects of viscosity and heat conduction. It is to be expected, however, that these dissipative mechanisms will produce observable effects on shocks which travel great distances. Since such shocks are now of considerable importance, we have attempted to examine theoretically the effect of viscosity and heat conduction on them. In this first investigation the shock has been assumed to be so weak that all nonlinear effects can be neglected and the usual acoustic equations applied.
