Abstract：Innuclearindustry，cycloneseparatorisoftenusedfor gas-solidseparationincircumstancessuchas transporting， processng anddust-controlingof uraniumcompound powders.Inthis study，theinfluenceof temperatureontheseparation performanceandflow fieldofacyclone separatorwas simulated byusing thecommercial software Barracuda basedonthe MPPIC model.Theaimofthis studyistotestthefeasibilityofMP-PICmodel inpredicting theperformanceofthecycloneseparator.TheresultsshowthattheMP-PIC modelcansimulatethe influencetrendsof inletgasvelocityandtemperatureon the performanceindicatorsof thecyclone separator.The predicted performanceandflow field parameter variationlawsaregenerallingoodagrementwiththeexperimentalresults.However，thepredictedvortexstrength isquantitativelyweakerhanexperimentalresults，andthis ismainlyreflected inthefactthatthepressuredropandgasvelocityobtainedfromthesimulation areboth tosome extentlowerthan theexperimentalvalues.This isrelated tothelargeeddyturbulencemodelandtherelatively low grid resolution used in the simulation.
