摘要：

The necessary condition for the formation and dissolution of the dissipative structure in particle-fluid two-phase flow has been investigated, revealing its origin in the compromise between the movement tendencies of the particles and the fluid. As soon as either the particles can dominate the fluid, or the fluid can dominate the particles, the dissipative structure either dissolves or a newly formed coexisting uniform structure appears. At this transition point, operating conditions and material properties alone become insufficient to ensure the steady state. Quantification of such a complicated structure calls for some mode of multiple resolution, for instance, it could be resolved with respect first to scale and then to amplitude and periodicity.
