Abstract : The combustion processes of an electrothermal chemical (ETC) gun depend strongly upon the entrainment and breakup of liquid propellant droplets into the Taylor cavity occupied mostly by high-temperature plasma, combustion product gases, and dispersed fine droplets. This report summarizes the existing empirical correlations for entrainment rates. The critical review of these correlations and their applicability to ETC gun environments is given. The required work for future development of a more adequate entrainment correlation, excluding the effect of droplet deposition to the liquid propellant, is proposed.
