Interaction of an incident shock wave (with a rectangular or triangular profile behind
its front) with a finite-width semi-infinite cloud of aluminum particles located in a
channel along the plane of symmetry is numerically simulated. Shock-wave interaction
with the leading edge of the cloud results in the formation of a vortex that leads to
cloud dispersion. Reflection of the curved shock wave from the plane of symmetry
may be regular or may include the formation of the Mach stem. If the cloud is loaded
by a rather strong shock wave, a detonation wave is formed in the cloud. In this
case, the flow is periodic, which is caused by passing of transverse waves and their
reflection from the walls.
