The conversion of internal to kinetic energy as typically occurs in many propulsive nozzles is characterized by atomic recombination of chemical species and by a peculiar behaviour of the vibrational energy. These phenomena can be simulated by models with different level of complexity. Here a comparison is shown among models based on the hypotesis of perfect gas, frozen and nonequilibrium regimes for the chemical reactions, equilibrium and frozen vibrational energy. From the comparison of the results the different influence of each phenomenon on the accuracy of the prediction is evaluated.

Abstract
The conversion of internal to kinetic energy as typically occurs in many propulsive nozzles is characterized by atomic recombination of chemical species and by a peculiar behaviour of the vibrational energy. These phenomena can be simulated by models with different level of complexity. Here a comparison is shown among models based on the hypotesis of perfect gas, frozen and nonequilibrium regimes for the chemical reactions, equilibrium and frozen vibrational energy. From the comparison of the results the different influence of each phenomenon on the accuracy of the prediction is evaluated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
