Abstract
Abstract The grade efficiency of fine particles is relatively inefficient for conventional cyclones, but the grade efficiency of the Radial Jet Cyclone (RJC) exceeds 90% for particles larger than 4 μm. The pressure drop of this cyclone is discussed based on the continuity equation, and a theoretical model is used to predict the pressure drop over the cyclone. Experimental results is in good agreement with the calculation. The inner flow field of cyclone is simulated by Reynolds Stress Model (RSM), and it indicates that there is a larger tangential velocity compared with the Stairmand Cyclone (SC) under the same inlet velocity. It reveals that the local loss in cushion chamber is in a significant proportion to pressure drop.
