Abstract
There is a need to clean various liquids of solid impurities in almost all areas of human activity. The filter design with a rotating cylindrical perforated filter element was proposed to address this topical technical problem. Its work based on the principle of rotational filtration. The experimental studies demonstrated that with a rotating cylindrical perforated filter element could remove more than 90% of the admixture particles. This took place in defined fluid motion modes, which characterized by the dimensionless Reynolds numbers. In the present study, numerical simulation was carried out for an investigation of the hydraulic oil motion and solid admixture particles' motion in the filter. The simulation results showed a local increase velocity in the holes of the perforated filter element. It entails the passage of a very small particle number into the filtrate. A comparison of the numerical simulation results of filter cleaning efficiency with the data of physical experiments showed a rather good agreement, the discrepancy between which is less than 9%.
