According　to　the　development　of　a　new　type　of　oil　purifier　HIGEE　rotating　oil　purifier,　this　paper　has　carried　out　related　numerical　simulations.　The　two-phase　porous　medium　flow　model　in　the　rotating　packed　bed　(RPB)　was　built,　and　by　using　CFD　software,　the　distribution　of　the　phases　in　the　RPB　which　is　on　the　condition　of　high　gravity　(HIGEE)　field　and　the　porous　media　has　been　simulated.　The　paper　has　developed　the　influencing　rule　of　key　technologies　parameters　which　affect　the　separating　efficiency　of　the　rotating　packed　bed.
