What is Experimental study of carbon particle charging at shock-wave pyrolysis of C3O2 about?
The temporal variation in electron and ion concentrations have been measured in shock-heated mixtures of Ar + (0-2)% C 3 O 2 in the 2000-3600 K temperature and 15-30 bar pressure range. Experiments in pure argon proved that the observed free electrons and ions originate from inherent impurities of sodium. The equilibrium concentrations of free charges in argon were established during (1-3) Â 10 À5 s and varied from 4 Â 10 11 cm À3 at T 5 = 2500 K to 5 Â 10 12 cm À3 at 3500 K. In the reactive mixtures, containing C 3 O 2 , the time profiles of electron and ion concentrations showed a more complicate behavior-a fast rise to a maximum followed by a gradual decay. The maximum ion concentrations were much higher and electron concentrations were much lower than in similar conditions in argon. The extent of the subsequent decay of electron concentration increased proportionally to the square of the C 3 O 2 concentration. In the mixture with 2% C 3 O 2 the final electron concentration was about 100 times less than in pure argon. The characteristic decay time of free charges varied from 400 to 40 ls and decreased proportionally to the square root of the charge concentration. The data analys
