Evaluation of Centrifugal Force, Erosion, Strain Rate, and Wall Shear in a Stairmand Cyclone

In the present study, imperative parameters including centrifugal force, erosion, streamline, strain rate, and wall shear are evaluated in a cyclone separator. The flaw of surface due to erosion is an acute problem industry. According great importance force on separation phenomenon, comprehensive study conducted. A computational fluid dynamics (CFD) simulation realized by applying Reynolds stress turbulence model (RSM), particle–air interactions were modeled using discrete phase (DPM). result shows good agreement between experimental data CFD tangential velocity pressure drop. maximum deviation validation process 6.8%. It found that within increased with enhancement inlet velocity. efficiency indicates increase–decrease treatment various velocities up 16 m⋅s−1 but decreases slightly at 20 m⋅s−1. increases proportionally best performance highest (99%) drop (416 Pa) obtains mass flow rate 0.01 kg⋅s−1. addition, was created entrance conical part cyclone.
