Numerical Investigation of Particle Transfer in an Hydraulic Oil Filter
Filtration is a common process in chemical engineering,fuel utilisation and fluid power transmission.An oil filter is a necessary and significant part in the fluid power system.Unlike the structure design and filter material selection,the particle movement in the filter during filtration is the fundamental factor for the filter performance,and this is not attracted enough attention.Due to the size and number of the particles in the filter,it is difficult to monitor every particle's movement during the filtration.Therefore,this work took a hydraulic oil filter as an example and applied discrete phase method to conduct a preliminary investigation on the particle movement in the filter,including how the flow rate and oil temperature affect the movement.The results showed that the flow rate of oil had a significant effect on the filtration speed but had little effect on the filtering efficiency.In comparison,different oil temperatures showed significant differences with in 0.3 s on the particle filtration but the steady states were similar.
