This paper is devoted to numerical modeling of combustion and detonation processes in aluminium aerosuspension clouds located in a plane channel under a shock-wave excitation. An incident shock wave is characterized by rectangular pressure profile or propagetes with an adjacent rarefaction wave. Different scenarios of detonation wave developing are obtained depending on the incident shock wave amplitude and profile. The critical values of initation total energy are calculated for different particle fractions. The problem of the shock wave interaction with the cloud of finite width is considered in 2-D nonsteady approximation. The diminishing of the coarse particle cloud width with respect to the channel cross-section leads to combustion zone arisen not to join the leading shock wave front that prevents the detonation structure formation. For fine particle clouds the detonation structure forms at the same conditions.
