Calculating the Chemical Compositions of Plasmas Generated by an Ablating-Capillary Arc

Abstract

The NASA-Lewis computer program for the calculation of complex chemical equilibrium compositions (CEA) is proposed as a means of characterizing the compositions of plasmas generated via an ablating-capillary arc. Results obtained with CEA are compared to those obtained with a Saha equation-based (SE) model with a limited reaction product set. Case studies conducted at temperatures from 5,000 to 20,000 K and pressures from 10 to 200 bar indicate that CEA warrants consideration for use in modeling such plasmas.
