| Abstract: | Experiment in the platform of flow grain system, flow characteristics of different size particles was obtained. Accurate calculation of suspension velocity and minimal fluidization speed can be obtained by means of numerical analysis. Pressure fluctuation signal was tested by spectrum analysis. Properties and components of pressure fluctuation signals were studied. |
