This paper reports on a procedure which leads to the assessment of the KG values without the need of determining the maximal rate of pressure rise by experiments. A simulation is proposed of the combustion process in its simplest form, i.e. one-dimensional propagation of the flame. Such simulation enables the burning velocity Su to be assessed. Knowing the Su values for different compositions of the flammable mixture makes it possible to determine the Su, max value. Once the correlation between Su,max and KG has been established, this will enable us to assign an appropriate value of KG to that of the maximal burning velocity. An example of such a correlation is given. It refers to flammable mixtures of a comparatively low burning velocity.
