摘要: | Steady, uniform, and free-surface flows of concentrated solid-liquid mixtures are studied experimentally by using a moving belt flume and stereo imaging methods. Measurements of particle motions inside the flows are obtained by using refractive index matched liquid and solid materials, and illuminating a subset of fluorescent particles using black light. The 3D positions of the particles are tracked using stereoscopic imaging. By capturing the trajectories of the fluorescent particles, we obtain measurements of mean velocity distribution, and for the first time, measurements of the granular temperature inside the flows. These measurements are compared with the predictions of kinetic theory. |
