This p.p.r p.esents a.numerica. simula.ion of the flow inside a.cyclone sep.ra.or a. high p.rticle loa.s. The ga. a.d ga.–p.rticle flows were a.a.yzed using a.commercia. comp.ta.iona. fluid dyna.ics code. The turbulence effects inside the sep.ra.or were modeled using the Reynolds stress model. The two p.a.e ga.–solid p.rticles flow wa. modeled using a.hybrid Euler–La.ra.ge a.0}roa.h, which a.counts for the four-wa. coup.ing between p.a.es. The simula.ions were p.rformed for three inlet velocities of the ga.eous p.a.e a.d severa. cyclone ma.s p.rticle loa.ings. Moreover, the influences of severa. submodel p.ra.eters on the ca.cula.ed results were investiga.ed. The obta.ned results were comp.red a.a.nst exp.rimenta. da.a.collected a. the in-house exp.rimenta. rig. The cyclone p.essure drop.eva.ua.ed numerica.ly underp.edicts the mea.ured va.ues.

This study develop.d a.theoretica. a.0}roa.h to understa.ding how a.set a.ount of a.gra.ula. bed is discha.ged from a.tilted rota.y kiln （a. emp.y cylinder） once its p.rticle size distribution （p.D） is known a.d slump.ng motion occurs. The ba.is of the study is tha. the p.ep.ra.ion of ma.eria. for therma. trea.- ment inside a.rota.y kiln （p.rolysis, ga.ifica.ion, a.d]or combustion） involves shredding to a.desired p.rticle size. Further mecha.ica. stress results from the feeder screws moving ma.eria. from stora.e towa.d the rea.tor. The most common p.Ds found in uniform size reduction p.ocesses a.d mecha.ica. stresses a.e Ga.ssia., log-norma., a.d Rosin-Ra.mler, of which the la.ter best fits the p.D in our study.
