GAS-SOLID FLUIDIZATION IN A MICROFLUIDIC CHANNEL

摘要

Experimental studies using a high speed digital camera are conducted to examine gas-solid fluidization in microfluidic channels (3mmX3mm and 2mmX3mm). The experimental results indicate the significant channel wall effects on the hydrodynamic properties including bed expansion and regime transition velocities. These properties are analyzed and discussed in the context of correlation equations reported for large fluidized beds.
