Modeling Study on Oil Particle Filtration Performance of a Composite Coalescing Filter

The traditional theoretical model is not suitable for the simulation of oil particle filtration process a composite filter due to its huge difference in fiber diameter. In this paper, concept dispersion σ was introduced into mathematical describing dynamic filter. results show that good agreement with experimental data. As packing density constant, higher dispersion, better performance is. addition, effect different factors on efficiency mechanisms discussed. For fine particles (<0.1 μm), diffusion dominant mechanism. coarse (>1 inertia impaction mechanism dominates efficiency. diameter has significant single-fiber by obviously affected velocity. an all except Moreover, such would contribute accurate prediction filters polydisperse and improve adjusting parameters reasonably.
