Abstract. In this paper, the wave pattern characteristics of results in single-phase nozzle flows of the pure gas, obvious
shock-induced two-phase nozzle flows with the quiescent or differences between these two kinds of flows can be seen. The
moving dusty gas ahead of the incident-shock front has been basic phenomena and features of the two-phase nozzle flows
investigated by using high-resolution numerical method. As by shock propagation are discussed in detail.
compared with the corresponding results in single-phase noz-
zle flows of the pure gas, obvious differences between these
two kinds of flows can be obtained.
