Probabilities of relaxation processes and characteristics of the vibrational kinetics of mixtures containing CO
Abstract
The vibrational kinetics of a mixture issuing from a nozzle is investigated with allowance for sublevel nonresonance exchange between CO and N2. The population distribution functions, gain characteristics, and power reserve are calculated for various expansion ratios and initial parameters. It is shown that although a gain as high as 1020 per m is achieved, the power reserve for expansion ratios of practical interest (less than 200) is rather low. The possibility of increasing power output by injecting cold Ar in a heated CON2 mixture in the critical nozzle section is examined.
