Descrição: A numerical simulation of a two-dimensional (2D) structure of the detonation wave (DW) in a two-fuel gaseous mixtures with air mixture at normal initial condition has been conducted. This study is based on a two-stage generalised model of detonation kinetics for a mixtures of two fuels first proposed by us. The computations have been performed in a wide range of channel height. The changes in the 2D front structure of the self-sustaining DW on variations of the height of the channel have been studied. From the analysis of the flow structure and the number of primary transverse waves in channel, the dominant sizes of the detonation cell for studied mixture have been determine. Numerical data on the detonation cell sizes have been carefully analyzed and compared with available experimental data.
