Governing equations for a relaxation region behind strong shock waves were solved numerically by the flux vector splitting method for pure nitrogen, based upon a multi-temperature (translation, rotation, vibration and electron) flow model. Chemical species of N, N_2, N^+, N_2^+ and e^-, and chemical reactions of dissociation-recombination, associative ionization and electron impact ionization were included in the calculation. As a dissociation rate coefficient for diatomic molecules, Jaffe's effective bond energy model was adopted, because the effects of multi-temperature should be included. As an energy transfer rate between translation and rotation energy modes, Lumpkin's model was used. Numerical results were compared with ISAS' experiments and two-boundary value numerical simulation. Calculated distributions of rotational and vibrational temperatures were reasonably in agreement with both the experiments and the two-boundary value solutions.
