ON THE ASSUMPTION OF SPECIFIC-HEAT RATIO NEAR ONE IN THE THEORY OF HIGH-ENERGY GAS FLOWS,
Abstract
The assumption that the ratio of specific heats is near one is of dominant importance in real-gas flow theory for hypersonic shock layers, scaling for dissociating flows, local similarity of the hypersonic boundary layer, and the theory of weak disturbances of a highly excited gas. Certain of these problems are briefly reviewed, chiefly to explain the advantages conferred by this assumption which, though poor a priori, has the power to unify diverse problems, often with surprising accuracy. Special attention is paid to the real-gas theory of sound waves, showing how a reduction of order is achieved for any process of energy release coupled with a state variable. Dispersal by chemical relaxation and by radiative transfer are described as examples. (Author)
