The Rankine-Hugoniot relation for a detonation wave has been numerically analyzed for hydrogen-oxygen mixture to evaluate its explosion pressure taking radical products at high temperature into consideration. The present study elucidates a scheme of convergence to the Jouguet point obtained by triple iterations over temperature, specific volume, and mole fractions of product gases. The total number of product gas atoms changes monotonously in the iteration over the mole fractions under the condition of constant temperature and specific volume. The final solution is, hence, obtained by the interpolation of the last two iteration points that extend the point where the total number of gas atoms is conserved. Every term of the Rankine-Hugoniot relation also changes monotonously in the iteration over the specific volume under constant temperature condition. So the final specific volume is determined in the same way as the mole fractions. In conclusion, the Jouget point with corresponding explosion pressure obtained dose not depend on the iteration steps or the truncation conditions.
