ABSTRACT:
A centrifuge is employed to continuously remove particulates from a fluid. In one embodiment, the centrifuge removes small particles of soot from lubricating oil of large diesel engines. The fluid in introduced into the centrifuge through an inducer so that vortexes are not propagated in the fluid. Flow constrainers and flow straighteners maintain laminar flow of the fluid as it passes axially through the centrifuge. An exducer decelerates the fluid prior to its exit from the centrifuge. The exducer thus contributes to maintaining laminar flow conditions. Laminar flow may contribute to the soot-removal effectiveness of the centrifuge.
