Abstract : A computer program describing the detailed thermochemistry and diffusional propagation which occur during the ignition of a combustible gaseous mixture has been written and tested. It is capable of describing the evolution in time and space of the temperature, pressure and species concentrations of a reacting system. In this report we restrict ourselves to homogeneous systems changing in time with or without temperature variation. In particular, the capabilities are illustrated of the code by comparing its predictions with various types of experimental data which are available for the hydrogen-oxygen system. It is also compared with an analytic model in order to highlight the principle chemical reactions involved. (Author)
