The use of lubrication oil is of many purposes and one among them is to drive the engine mounted on a ship. Hence the supply of cleanlubrication oil is important. And an oil purifier is one of key components in marine diesel engines. At present, the element type full-flow oil filter hasbeen widely used for cleaning the engine oil. The self-driven centrifugal oil purifier is a device which is used to remove the impurities in lubricationoil using a jet flow. The flow characteristics and the physical behaviors of particles in this self-driven oil purifier were investigated numerically andthe filtration efficiencies were evaluated. For calculations, a Computational Fluid Dynamics method is used and the Shear Stress Transport turbulencemodel has been adopted. The Multi Frames of Reference method is used to consider the rotating effect of the flows. The influence of centrifugalforcehas been numerically investigatedto improve filtration efficiency of tiny particles. As a result of this research, it was found that the particlefiltration efficiency using the only center axis rotating and outer wall rotating system are higher than that of the fully rotating system in the self-drivenoil purifier.
Abstract
The use of lubrication oil is of many purposes and one among them is to drive the engine mounted on a ship. Hence the supply of cleanlubrication oil is important.

The self-driven centrifugal oil purifier is a device which is used to remove the impurities in lubricationoil using a jet flow. The flow characteristics and the physical behaviors of particles in this self-driven oil purifier were investigated numerically andthe filtration efficiencies were evaluated. For calculations, a Computational Fluid Dynamics method is used and the Shear Stress Transport turbulencemodel has been adopted. The Multi Frames of Reference method is used to consider the rotating effect of the flows. The influence of centrifugalforcehas been numerically investigatedto improve filtration efficiency of tiny particles. As a result of this research, it was found that the particlefiltration efficiency using the only center axis rotating and outer wall rotating system are higher than that of the fully rotating system in the self-drivenoil purifier.
