摘要

The mixing dynamics of granular materials immersed in a liquid was experimentally studied in a quasi-2D rotating drum. A DV (SONY DCR-TRV900 NTSC) motion corder analyzer was used to record the motions of granular materials. The effects of interstitial fluid viscosity and filling degree on the mixing index, mixing rate constant, and dynamic repose angle in the rotating drum were investigated and discussed in this paper. The experimental results show that the interstitial fluid viscosity has almost not influence on the final stable mixing index but has significantly effects on the mixing rate constant and dynamic repose angle in slurry granular flows. The results show that the mixing rate and dynamic repose angle increase with increasing the interstitial fluid viscosity. The results also indicate that the filling degree plays an important role in mixing dynamics in slurry granular flows. The mixing rate constant is demonstrated to be decreased with increasing the filling degree. The dynamic repose angle is not altered by the filling degree. Finally, we find that the dynamic repose angle and the mixing rate constant increase slightly at high Stokes number and increase dramatically at low Stokes number with decreasing Stokes number.
