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.

已经对正常初始条件下与空气混合物的双燃料气体混合物中的爆震波 (DW) 的二维 (2D) 结构进行了数值模拟。本研究基于我们首次提出的两种燃料混合物的爆震动力学的两阶段广义模型。计算已经在很宽的通道高度范围内进行。已经研究了自持DW的2D前部结构随通道高度的变化而变化。通过对流动结构和通道内一次横波数量的分析，确定了所研究混合物的爆震室的主要尺寸。已经仔细分析了爆震室尺寸的数值数据，并与可用的实验数据进行了比较。
