Recombination processes of electrons in supersonic flows have been studied using the coupled set of continuity, momentum, energy, and appropriate rate equations. The solution of these equations for a one-dimensional supersonic nozzle flow gives rise to a useful similarity transformation. The similarity solution was found to have very good agreement with numerical solutions of the recombination problem. This analysis predicts the conditions and location in a nozzle for the electron temperature to freeze and also conditions required for the electron density to freeze. Example calculations are made for argon. This method is expected to be useful for studying systems using recombination effects such as magnetohydrodynamics lasers and chemical lasers. Author
