The Effects of the Blade Cascade and Deflecting Plate on the Flow Pattern of Solid particles and Wall Pressure Drop in the Vertical Cylinder

The flow pattern and the pressure drop in the fluidized and spouted beds were examined experimentally. Measurements of the pressure drop were made on the various angle β(=30,40,50,70 and 90 degrees) of the blade cascade and the various angle α(=0,10,20 and 30 degrees) and the various height e(=0,10,20 and 30mm) of the deflecting plate, and the flow patterns also have been observed by both the photograph and sketching. The results of these experiments are as follows : (1) The flow patterns of solid particles show the ”swirling” type flow when β=30&acd
