摘要: Abstract Differential pressure along the axis and local solids concentration in fully developed region were measured a high-density downer (0.025 m i.d., 5 m high). Chaos analysis was used to study non-linear multi-scale flow behavior downer. Local measurements global differential estimate correlation integral. Pressure fluctuations of showed bi-fractal behavior. Large-scale corresponded low dimension, small-scale high dimension. FCC particles more significant than glass beads. dynamics from contributed by many different scales, namely dispersed clusters sizes, so that there only one scaling log–log plot integral versus distance. Solids flux found significantly affect
