Thermodynamic properties calculation of air – water vapor mixtures thermal plasmas
Abstract
Knowledge of air-water vapor mixtures thermal plasmas thermodynamic properties is important to estimate the
performances of electrical arc cutting in this gas by a circuit breaker. In this paper, air-water vapor mixtures thermal
plasmas thermodynamic properties are calculated in a temperature range from 5000K to 30000K. The calculations are
carried out by supposing local thermodynamic equilibrium at pressure of 1; 5 and 10 atm. The obtained results show
the influence of the water vapor initial proportion but also that of the pressure on these plasmas thermodynamic
properties.
Keywords: Mixture; plasma composition; thermal plasma; thermodynamic properties; circuit breakers.
