Abstract

In order to simplify the calculation and analysis process, the the difference of shape and size of cereal grain shaped particles was converted to projected diameter. Using the theory of multiphase flow, resistance coefficient, fluid drag force and relaxation time of entrance flow on single grain particle and grain particles of dilute phase and dense phase flow conveying were researched. The results showed that the different kind of grain particle can be characterized as volume shape factor and projected diameter. The fluid drag force of single grain particles or particles in different regions with different Reynolds number have different variation. The same type of particles is also affected by projection diameter, suspension speed and other parameters. The inlet relaxation time of the dense phase transport particle group is higher than that of dilute phase transport, and the single particle fluidization relaxation time is one order of magnitude. Different kinds of raw material grains flow of the relaxation time is different, so the energy consumption to achieve the suspended feed status is also different.
