The one-dimensional flow equation for mass flow through the throat of a supersonic nozzle has been modified for use with real gas values of gamma and compressibility. Curve fits for gamma and Z and a simple iteration scheme have been developed for use with air and nitrogen over a temperature range of 300 to 6000 deg. K and a pressure of 10 to 100 atm. With this approach the sonic throat method can be used with the most recent gas tables to determine high temperature wind tunnel supply temperatures or enthalpies. (Author).

It is well established that population inversions between the (001) and (100) vibrational energy levels of CO2 can be created by rapid expansions of CO2-N2-H2O or He mixtures through supersonic nozzles. New experimental results are presented for such inversions. These experiments were conducted in both the 3-Megawatt Arc Tunnel and the 12.7 cm Shock Tunnel at the Naval Ordnance Laboratory. The results support previously published theoretical predictions obtained with a numerical, time-dependent, nonequilibrium nozzle flow analysis employing a simplified vibrational kinetic model. This theory is also compared with experimental data obtained by other investigators. (Author).

One-dimensional Compressible Flow is an introduction to compressible flow. The book covers the main concepts from thermodynamics and fluid mechanics, including the continuity and momentum equations and the laws of thermodynamics; the steady flow with area change, friction, or heat transfer; and the one-dimensional steady flow. The text also gives an introduction to the method of characteristics for solving unsteady flow problems. Charts and tables are provided in the book for performing steady flow calculations. The book is useful to students pursuing a degree course in mechanical engineering and practicing mechanical engineer.
