Abstract : A new technique for the computation of inviscid flows with finite rate chemistry is presented. The case of hydrogen-air combustion is studied in full detail, but this technique can be applied to other mixtures. Difficulties due to instability in existing techniques are eliminated. Consequently, the stepsize in the numerical finite difference procedure can be increased by 2 to 4 orders of magnitude. Lengthy calculations which make the programming of two-dimensional flows with finite rate chemistry uneconomical are reduced to a few seconds on a high-speed computer. A comparison of results of this technique with that of other techniques is presented. (Author)
