论文摘要
碎片流的内部行为为对其运动负责的力学提供了基本的见解。我们在小规模的实验碎屑流中提供速度数据，包括沿矩形水槽瞬时释放水颗粒混合物，倾斜在31度。结果表明，从碰撞，湍流的前部到粘性型，稳定的流动体，表现出强烈的流体局促耦合。这是第一次考虑了小规模碎片流的内部力学的空间和时间演变。我们的结果是测试两相流体局部数值模型的宝贵数据。
The internal behaviour of debris flows provides fundamental insight into the mechanics responsible for their motion. We provide velocity data within a small-scale experimental debris flow, consisting of the instantaneous release of a water-granular mixture along a rectangular flume, inclined at 31 degrees. The results show a transition from a collisional, turbulent front to a viscous-type, steady flow body, exhibiting strong fluid-particulate coupling. This is the first time that both the spatial and temporal evolution of the internal mechanics of a small-scale debris flow have been considered. Our results serve as invaluable data for testing two-phase fluid-particulate numerical models.
