Abstract : A detailed description of a computer code to predict the influence of electrophilic liquid injection on re-entry plasma sheath properties is presented. The code requires input data on the liquid injection system parameters (i.e. electrophilic liquid properties, injection velocity, number of orifices, etc.) and the plasma sheath (shock layer) properties for no material addition, and predicts altered shock layer flow properties and species concentrations. Of primary interest is the ability of the code to predict reductions in shock layer electron concentrations, which determine the effectiveness of the injectant in alleviating re-entry blackout.
